REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

To STARWOOD HOTELS & RESORTS WORLDWIDE, INC. SAVINGS AND RETIREMENT PLAN

We have audited the accompanying statement of net assets available for benefits of Starwood Hotels & Resorts Worldwide, Inc. Savings and Retirement Plan (the “Plan”) at December 31, 2007, and the related statement of changes in net assets available for benefits for the year ended December 31, 2007. These financial statements are the responsibility of the Plan’s management. Our responsibility is to express an opinion on these financial statements based on our audit.

We conducted our audit in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement. An audit includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements. An audit also includes assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall financial statement presentation. We believe that our audit provides a reasonable basis for our opinion.

In our opinion, the 2007 financial statements referred to above present fairly, in all material respects, the net assets available for benefits of the Plan at December 31, 2007, and the changes in its net assets available for benefits for the year ended December 31, 2007, in conformity with U.S. generally accepted accounting principles.

Our audit was performed for the purpose of forming an opinion on the 2007 basic financial statements taken as a whole. The supplemental schedule of assets (held at end of year) is presented for purposes of additional analysis and is not a required part of the 2007 basic financial statements, but is supplementary information required by the Department of Labor’s Rules and Regulations for Reporting and Disclosure under the Employee Retirement Income Security Act of 1974. The supplemental schedule is the responsibility of the Plan’s management. The supplemental schedule has been subjected to the auditing procedures applied in the audit of the 2007 basic financial statements and, in our opinion, is fairly stated in all material respects in relation to the 2007 basic financial statements taken as a whole.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

To the Starwood Hotels & Resorts Worldwide, Inc. Savings and Retirement Plan:

We have audited the accompanying statement of net assets available for benefits of the Starwood Hotels & Resorts Worldwide, Inc. Savings and Retirement Plan (the “Plan”) as of December 31, 2006. This financial statement is the responsibility of the Plan’s management. Our responsibility is to express an opinion on this financial statement based on our audit.

We conducted our audit in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statement is free of material misstatement. We were not engaged to perform an audit of the Plan’s internal control over financial reporting. Our audit included consideration of internal control over financial reporting as a basis for designing audit procedures that are appropriate in the circumstances, but not for the purpose of expressing an opinion on the effectiveness of the Plan’s internal control over financial reporting. Accordingly, we express no such opinion. An audit also includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statement, assessing the accounting principles used and significant estimates made by management, and evaluating the overall financial statement presentation. We believe that our audit provides a reasonable basis for our opinion.

In our opinion, the financial statement referred to above presents fairly, in all material respects, the net assets available for benefits of the Plan at December 31, 2006, in conformity with U.S. generally accepted accounting principles.

STARWOOD HOTELS & RESORTS WORLDWIDE, INC.
SAVINGS AND RETIREMENT PLAN

NOTES TO FINANCIAL STATEMENTS

December 31, 2007 and 2006

(1)	Description of the Plan
	The following description of the Starwood Hotels & Resorts Worldwide, Inc. Savings and Retirement Plan (the “Plan”) provides only general information. Participants should refer to the Plan summary for a more complete description of the Plan’s provisions.
	Starwood Hotels & Resorts Worldwide, Inc. (“Starwood” or the “Company”) sponsors the Plan administered by the Starwood Benefits Committee (the “Plan Administrator”). The Plan was originally established effective April 1, 1997.
	General
	The Plan is a defined contribution plan, subject to the provisions of the Employee Retirement Income Security Act of 1974 (“ERISA”). The Plan provides for employee pretax and matching employer contributions in accordance with Section 401(k) and 401(m) of the Internal Revenue Code (“IRC”). The Plan’s assets are held in trust pursuant to a trust agreement with the Company and State Street Bank and Trust Company (“State Street”).
	Eligibility
	Company employees become eligible to participate in the Plan when they are at least 21 years of age and have completed a three-month period of service. The Company does not begin to match contributions until the participant has completed one year of service as defined by the Plan.
	Contributions
	Plan participants may elect to make pretax contributions as a percentage of compensation up to 18% of compensation, subject to Internal Revenue Service limitations. The Company makes a matching contribution in an amount equal to 100% of the initial pretax contributions up to 2% of eligible compensation and 50% of the pretax contributions between 2% and 4% of the participant’s eligible compensation. Participants direct the investment of their contributions and the Company’s matching into various investment options offered by the Plan.
	Participants who are age 50 or older by the end of the applicable plan year and have contributed the maximum pretax contributions allowable by the Plan during the plan year may make an additional pretax catch-up contribution. The catch-up contribution was limited to $5,000 for 2007.
	Corrective distributions of $1,406,708 and $1,295,283 for the Plan years ended December 31, 2007 and December 2006, respectively, are payments made to certain active participants to return to them excess deferral contributions. The return of excess contributions is required to satisfy the relevant nondiscrimination tests of the Plan for the year.
	Vesting
	Participants are immediately vested in their voluntary contributions and earnings thereon. Participants become 100% vested in the Company’s contributions and earnings thereon after three years of service.
	Rollover contributions and distributions
	Participants entering the Plan may roll over contributions from a trust, individual retirement account (“IRA”) or individual retirement annuity qualified under the IRC no later than the 60th day following the day on which the individual receives the distribution. Participants leaving the Plan may request rollover distributions to the qualified plan of another employer, an IRA account or to an insurance company IRA annuity.

NOTES TO FINANCIAL STATEMENTS

December 31, 2007 and 2006

(1)	Description of the Plan (continued)
	Participants’ accounts
	Separate accounts are maintained with respect to Plan participants’ pretax contributions, employer matching contributions, and rollover contributions. Each participant’s account is credited with the appropriate contributions and allowance of investment earnings and losses and charged with Plan investment expenses. Allocations of Plan earnings/losses and expenses are based on the proportion of each participant’s account balance to the total of all account balances for each investment type.
	Participant loans
	Participants may borrow from the vested portion of their accounts. The minimum loan amount is $1,000, restricted to 50% of the participant’s vested account balance. The maximum amount a participant may borrow is equal to the lesser of $50,000 or 50% of their vested account balance, reduced by any outstanding loan balance. A participant may have no more than two loans outstanding at one time. The repayment period may not exceed five years from the date of the loan, unless the loan proceeds are used to acquire the participant’s principal residence. The loans are collateralized by the balance in the participant’s account and bear interest at a fixed rate equal to the prime interest rate as of the first business day of the month when the loan was issued, plus 1%. For 2007 and 2006, the loan interest rate averaged 9.1% and 8.9%, respectively. Loans outstanding at December 31, 2007 and 2006, totaled $27,287,813 and $23,745,607, respectively.
	Payment of benefits
	Participants are eligible for distribution of vested benefits upon retirement, death, disability or termination of employment. Participants may elect to receive a lump-sum amount or, subject to certain conditions, equal monthly or annual installments over a period not greater than 20 years. Participants may also elect to defer distributions subject to certain conditions.
	Withdrawals of a participant’s vested benefits are also permitted upon attainment of age 59-1/2 or, subject to Plan provisions, as a hardship distribution.
	Forfeitures
	Forfeitures of the nonvested Company contributions are applied to reduce future Company contributions. Unallocated forfeited nonvested accounts totaled $184,147 and $435,661 at December 31, 2007 and 2006, respectively. During 2007, forfeited nonvested accounts reduced Company contributions by $1,513,203.
	Administrative expenses
	Administrative expenses, including investment management and recordkeeping fees, are paid from Plan assets, except to the extent the Company pays such expenses. For the year ended December 31, 2007, substantially all administrative expenses were paid by the Plan. Loan processing fees are deducted from the accounts of participants who have requested loans.

NOTES TO FINANCIAL STATEMENTS

December 31, 2007 and 2006

(1)	Description of the Plan (continued)
	Termination of the Plan
	Although it has not expressed any intent to do so, the Company has the right under the Plan agreement to suspend, reduce, or partially or completely discontinue its contributions at any time and to terminate the Plan, the trust agreement, and the trust thereunder, subject to the provisions of ERISA. In the event of Plan termination, partial termination or complete discontinuance of contributions, participants become fully vested in the Company contributions. Additionally, any forfeitures that have not been used to reduce Company contributions to the Plan as of the termination will be credited pro rata to the accounts of all participants in accordance with Plan provisions.
(2)	Summary of significant accounting policies
	Basis of accounting
	The accompanying financial statements have been prepared on the accrual basis of accounting. Accordingly, income is recognized when earned and expenses are recorded when incurred.
	Use of estimates
	The preparation of financial statements in conformity with U.S. generally accepted accounting principles requires the Plan Administrator to make estimates and assumptions that affect the reported amount of assets, liabilities and net assets and the reported amount of additions to and deductions from net assets. Actual results could differ from those estimates.
	Concentration of credit risk and market risk
	The Plan provides for various investment fund options which in turn invest in any combination of stocks, bonds and other investment securities. Investment securities are exposed to various risks, such as interest rate, market and credit risks. The Plan’s risk of credit loss is limited to the carrying value of the investments. Due to the level of risk associated with certain investment securities, it is at least reasonably possible that changes in risks in the near term could materially affect participants’ account balances and the amounts reported in the statements of net assets available for benefits and the statement of changes in net assets available for benefits.
	Investments
	The Plan’s investments in mutual funds, Starwood common stock and money market funds are presented at fair value and fair value is determined by using quoted market prices from commercial quotation services as of the Plan year-end. Fair value of common collective trusts is determined by State Street based on the quoted market values of the underlying securities. Participant loans are valued at cost which approximates fair value.

December 31, 2007 and 2006

(2)	Summary of significant accounting policies (continued)
	As described in Financial Accounting Standards Board Staff Position (FSP) AAG INV-1 and SOP 94-4-1, Reporting of Fully Benefit-Responsive Investment Contracts Held by Certain Investment Companies Subject to the AICPA Investment Company Guide and Defined-Contribution Health and Welfare and Pension Plans (the FSP), investment contracts held by a defined contribution plan are required to be reported at fair value. However, contract value is the relevant measurement attribute for that portion of the net assets available for benefits of a defined contribution plan attributable to fully benefit-responsive investment contracts because contract value is the amount participants would receive if they were to initiate permitted transactions under the terms of the Plan. The Plan invests in investment contracts through a common collective trust. As required by the FSP, the statement of net assets available for benefits presents the fair value of the investment in the common collective trust as well as the adjustment of the investment in the common collective trust from fair value to contract value relating to the fully benefit-responsive investment contracts. The statement of changes in net assets available for benefits is prepared on a contract value basis.
	Purchases and sales of securities are recorded on a trade-date basis. Interest income is recorded on the accrual basis. Dividends are recorded on the ex-dividend date.
	Benefits paid to participants
	Benefits paid to participants are recorded in the period in which they are paid.
	Assets transferred from other plans, net
	Assets transferred from or to other plans represent transfers of participant account balances whenever a participant changes employment between the Company and a nonaffiliate of Starwood who has elected to adopt the Starwood Hotels & Resorts Worldwide, Inc. Savings and Retirement Plan as a mirror plan.
(3)	Investments
	The following investments, along with their respective percentage of net assets available for benefits, represent 5% or more of the Plan’s net assets available for benefits at December 31:

	2007				2006
State Street Bank and Trust Company Principal Accumulation Return Fund	$	163,929,186	24	%	$	155,023,581	25	%

NOTES TO FINANCIAL STATEMENTS

December 31, 2007 and 2006

(3)	Investments (continued)
	The Plan’s investments (including gains and losses on investments purchased and sold, as well as held during the year) appreciated (depreciated) in value as follows for the year ended December 31:

	2007
Common collective trusts	$	9,311,798
Mutual funds		6,370,129
Starwood Hotels & Resorts Worldwide, Inc. Common Stock		(24,663,857	)
	$	(8,981,930	)

(4)	Tax status
	The Plan received a favorable determination letter from the IRS dated October 8, 2003. The determination letter was applicable for amendments adopted by the Plan through January 8, 2002. Subsequent to this determination by the IRS, the Plan was further amended. Effective January 1, 2006, the Plan was restated to adopt all prior amendments to the Plan. Subsequent to the Plan restatement, the Plan was further amended. Although the Plan has been amended and restated since receiving the determination letter, the Plan Administrator believes that the Plan is designed and operated in compliance with the applicable requirements of the IRC and that the Plan was qualified and the related trust was tax-exempt as of December 31, 2007.
(5)	Party-in-interest transactions
	Certain Plan investments are held in funds managed by State Street and Legg Mason Investor Services, LLC, an affiliate of State Street; therefore, these transactions qualify as party-in-interest transactions. In addition, certain Plan investments are in Starwood common stock, qualifying these transactions as party-in-interest transactions. Fees incurred by the Plan for the investment management services amounted to $285,500 for the year ended December 31, 2007.
	The Company also charges the Trust for an allocation of certain administrative costs. The Company is the Trust sponsor; therefore, these transactions qualify as party-in-interest transactions. Total costs charged to the Trust were $289,865 for the year ended December 31, 2007.
