SUNSTONE HOTEL INVESTORS REPORTS RESULTS OF OPERATIONS FOR

FIRST QUARTER 2006

Adjusted FFO Per Share up 19.5% and RevPAR up 9.0%;

To Acquire La Jolla Embassy Suites

SAN CLEMENTE, CA – May 3, 2006 – Sunstone Hotel Investors, Inc. (the “Company”) (NYSE: SHO) today announced results of operations for the first quarter ended March 31, 2006.

FIRST QUARTER 2006 HIGHLIGHTS

• Same-store revenue per available room (“RevPAR”) growth of 9.0%, excluding two assets undergoing rebranding and renovation programs (Fairmont Newport Beach and Hyatt Regency Century Plaza), and 6.7% overall over first quarter 2005;

• Adjusted EBITDA of $52.0 million (78.1% increase over first quarter 2005);

• Adjusted Funds From Operations (“Adjusted FFO”) to common stockholders of $29.2 million (87.2% increase over first quarter 2005); and

• Adjusted FFO per diluted share of $0.49 (19.5% increase over first quarter 2005).

Robert A. Alter, Chief Executive Officer, stated, “We have had an excellent start to 2006 at Sunstone. During the first quarter, we acquired the Del Mar Marriott in San Diego and the Hilton Times Square in New York City. Both of these properties are high quality assets in high barrier to entry markets. Our existing hotel portfolio has performed well as evidenced by our solid year over year RevPAR gains. The rebranding and renovation program at the Fairmont Newport Beach has been substantially completed. Our expectations are high for this hotel going forward. Finally, we are encouraged about 2006 as hotel market fundamentals remain strong and our portfolio continues to post outstanding results from operations.”

ACQUISITION OF LA JOLLA EMBASSY SUITES

The Company has signed an agreement to acquire the Embassy Suites in La Jolla, California and expects to close this transaction in May 2006. The 335-room all-suite hotel will be acquired for approximately $100 million, or approximately $300,000 per suite. The hotel will continue to be managed by Hilton Hotels Corporation. Built in 1987, the hotel is well located in the University Town Center submarket of San Diego, fifteen minutes north of downtown and the airport. The hotel is located on La Jolla Village Drive, in the heart of San Diego’s “Golden Triangle”, the area bounded by the 5 freeway to the west, the 805 freeway to the east and the 52 freeway to the south. The surrounding office market includes approximately six million square feet of space, occupied primarily by hi-tech, biomedical, pharmaceutical and defense contracting firms. The Company will also spend approximately $9 million to renovate the hotel. The purchase price is approximately 13.7x estimated 2006 EBITDA and 11.4x estimated 2007 EBITDA (a reconciliation of the hotel’s EBITDA to net income is provided in the Annual 2006 Outlook section).

Performance Relative to Guidance

The following table reflects our prior guidance for the first quarter 2006 compared to our actual results.

	Guidance	Actual First Quarter 2006
RevPAR Growth	6.0% to 8.0%	9.0% excluding two hotels undergoing rebranding and renovation programs and 6.7% overall
Adjusted EBITDA	$50 million to $52 million	$52.0 million
Adjusted FFO available to common stockholders per diluted share	$0.44 to $0.47	$0.49
Hotel Operating Profit Margin	+150 bps to 200 bps	+160 bps

Comparable RevPAR for 59 hotels, which excludes 2 hotels undergoing rebranding and renovation programs (Fairmont Newport Beach and Hyatt Regency Century Plaza), owned during the first quarter 2006 (including prior ownership periods for acquisitions) increased 9.0% as compared to the first quarter of 2005, driven by an increase of 8.5% in average daily room rate and 0.3 occupancy points. RevPAR performance for the entire portfolio, while strong, was negatively impacted by rebranding and renovation programs at two of the Company’s hotels. Including these two hotels, RevPAR increased 6.7% driven by an increase in average daily rate.

Comparable hotel operating profit margins for the first quarter increased 160 basis points (from 26.1% to 27.7%) (see page 11 for a reconciliation of hotel operating income to the comparable GAAP measure).

The first quarter was negatively impacted by the delayed closing of the Hilton Times Square acquisition. Prior guidance assumed a closing date of March 1, 2006. The acquisition was completed on March 20, 2006 resulting in approximately $0.9 million less EBITDA than had been assumed in our prior guidance.

In addition to the Fairmont Newport Beach and Hyatt Regency Century Plaza, significant renovation work was completed at a number of our hotels which resulted in disruption to first quarter operations. Please see “Capital Expenditures” on page 5 for more detail.

Outlook

The Company is providing guidance at this time but does not undertake to update it for any developments in its business. Achievement of the anticipated results is subject to risks and uncertainties, including those disclosed in the Company’s filings with the Securities and Exchange Commission. The Company has

3

provided guidance for the second quarter of 2006 as well as full year 2006. The Company’s guidance does not include the impact of any possible future asset sales. The guidance also assumes a May 17, 2006, closing on the acquisition of the Embassy Suites, La Jolla, California.

Second Quarter 2006 Outlook

The Company expects comparable hotel RevPAR for the second quarter of 2006 to increase approximately 7.0% to 9.0% over the second quarter of 2005. As a result, the Company estimates that for the second quarter of 2006:

• Income available to common stockholders should be approximately $13.3 million to $16.3 million;

• Adjusted EBITDA should be approximately $69.0 million to $72.0 million;

• Adjusted FFO available to common stockholders should be approximately $43.1 million to $46.1 million;

• Adjusted FFO available to common stockholders per diluted share should be approximately $0.69 to $0.74;

• Hotel operating profit margins should increase approximately 150 basis points to 200 basis points over the second quarter of 2005; and

• Total cash paid for improvements to hotel properties should be $40 million to $50 million.

Due to the sale of the Hollywood Holiday Inn, second quarter guidance for EBITDA has been negatively impacted by approximately $0.6 million as compared to assumptions used in our prior guidance.

Annual 2006 Outlook

The Company reiterates the previously provided guidance that it expects comparable hotel RevPAR for the full year 2006 to increase approximately 7% to 9% over the full year 2005. As a result, the Company estimates that for the full year 2006:

• Income available to common stockholders should be approximately $37.2 million to $43.2 million;

• Adjusted EBITDA should be approximately $257 million to $263 million;

• Adjusted FFO available to common stockholders should be approximately $155.9 million to $161.9 million;

• Adjusted FFO available to common stockholders per diluted share should be approximately $2.52 to $2.62;

• Hotel operating profit margins should increase approximately 150 basis points to 200 basis points over the full year 2005; and

• Total cash paid for improvements to hotel properties should be $125 million to $140 million.

Due to the sale of the Hollywood Holiday Inn, full year guidance for EBITDA has been negatively impacted by approximately $1.7 million as compared to assumptions used in our prior guidance. Additionally, the delayed closing of the Hilton Times Square resulted in an approximately $0.9 million reduction to projected full year 2006 EBITDA as compared to the assumptions used in our prior guidance. From the expected acquisition date of May 17, 2006 through year end, the La Jolla Embassy Suites is expected to generate $0.1 million of net income available to common stockholders, depreciation expense of $1.6 million, and interest expense of $2.9 million, resulting in EBITDA of $4.6 million. Including the period prior to our anticipated May acquisition, full year 2006 EBITDA for this hotel is estimated at $7.3 million based on $0.2 million of income available to common stockholders, $2.5 million of depreciation expense and $4.6 million of interest expense and full year 2007 EBITDA for this hotel is estimated at $8.8 million based on

4

$1.7 million of income available to common stockholders, $2.5 million of depreciation expense and $4.6 million of interest expense. Depreciation expense for this hotel is an estimate based on the purchase price and may change depending on the final purchase price allocation.

Balance Sheet/Liquidity Update

As of March 31, 2006, the Company had approximately $76.6 million of cash and cash equivalents (including restricted cash). The Company also had $112.7 million of availability under its $150.0 million credit line and has 15 unencumbered assets, including the Fairmont Newport Beach. Total assets were $2.6 billion, including $2.4 billion of net investments in hotel properties, total debt of $1.4 billion and stockholders’ equity of $1.0 billion.

In January 2006, the Company completed the acquisition of the 284-room Marriott Del Mar located in San Diego, California for approximately $69.1 million.

In February 2006, the Company closed a public offering of 5.5 million shares of common stock for net proceeds of approximately $158.1 million. The proceeds from this offering were used to fund a portion of the acquisition price of the Hilton Times Square Hotel.

In March 2006, the Company completed the acquisition of the 444-room Hilton Times Square Hotel located in New York, New York for approximately $256.3 million which includes a $15.0 million payment to convert the hotel to a franchise. The Company financed the acquisition primarily through the assumption of $81.0 million of debt due in 2010 with a rate of 5.9% per annum and proceeds from its February 2006 common stock offering.

In March 2006, the Company sold to an unrelated third party the Hollywood Holiday Inn located in Los Angeles, California for approximately $25.5 million.

In March 2006, the Company refinanced two existing mortgage loans that would have matured in 2008. The Company incurred a prepayment penalty of approximately $7.4 million to defease the loans. Key terms are as follows (dollars in millions):

	Prior Loan					New Loan
	Amount		Rate		Maturity	Amount		Rate		Maturity
Houston Wyndham	$	35.8	8.25	%	2008	$	34.0	5.66	%	2016

Non-GAAP Financial Measures

We present the following non-GAAP financial measures that we believe are useful to investors as key measures of our operating performance: (1) Earnings Before Interest Expense, Taxes, Depreciation and Amortization, or EBITDA; (2) Adjusted EBITDA (as defined below); (3) Funds From Operations, or FFO; (4) Adjusted FFO (as defined below); and (5) Hotel Operating Income for the purpose of our operating margins.

EBITDA represents income (loss) available to common stockholders before minority interest excluding: (1) preferred stock dividends; (2) interest expense (including prepayment penalties, if any); (3) provision for income taxes, including income taxes applicable to sale of assets; and (4) depreciation and amortization. In addition, we have presented Adjusted EBITDA, which excludes: (1) the impact of any gain or loss from asset sales: (2) impairment charges; and (3) other adjustments we have identified in this release. We believe EBITDA and Adjusted EBITDA are useful to an investor in evaluating our operating performance because they help investors evaluate and compare the results of our operations from period to period by removing the impact of our capital structure (primarily interest expense and preferred stock dividends) and our asset base (primarily depreciation and amortization) from our operating results. We also use EBITDA and Adjusted EBITDA as measures in determining the value of hotel acquisitions and dispositions. A reconciliation and the components of hotel operating income are set forth on page 13. We believe hotel operating income is also useful to investors in evaluating our property level operating performance.

We compute FFO in accordance with standards established by the National Association of Real Estate Investment Trusts, or NAREIT, an industry trade group. The Board of Governors of NAREIT in its March 1995 White Paper (as clarified in November 1999 and April 2002) defines FFO to mean net income (loss) (computed in accordance with GAAP), excluding gains and losses from sales of property, plus real estate-related depreciation and amortization (excluding amortization of deferred financing costs), and after adjustment for unconsolidated partnerships and joint ventures. We also present Adjusted FFO which excludes prepayment penalties, written-off deferred financing costs, impairment losses and other adjustments we have identified in this release. We believe that the presentation of FFO and Adjusted FFO provide useful information to investors regarding our operating performance because they are a measure of our operations without regard to specified non-cash items such as real estate depreciation and amortization, gain or loss on sale of assets and certain other items which we believe are not indicative of the performance of our underlying hotel properties. We believe that these items are more representative of our asset base and our acquisition and disposition activities than our ongoing operations. We also use FFO as one measure in determining our results after taking into account the impact of our capital structure. A reconciliation of net income (loss) to FFO and Adjusted FFO is set forth on page 10.

We caution investors that amounts presented in accordance with our definitions of EBITDA, Adjusted EBITDA, FFO, Adjusted FFO and hotel operating income may not be comparable to similar measures disclosed by other companies, since not all companies calculate these non-GAAP measures in the same manner. EBITDA, Adjusted EBITDA, FFO, Adjusted FFO and hotel operating income should not be considered as an alternative measure of our net income (loss), operating performance, cash flow or liquidity. EBITDA, Adjusted EBITDA, FFO, Adjusted FFO and hotel operating income may include funds that may not be available for our discretionary use due to functional requirements to conserve funds for capital expenditures and property acquisitions and other commitments and uncertainties. Although we believe that EBITDA, Adjusted EBITDA, FFO, Adjusted FFO and hotel operating income can enhance an investor’s understanding of our results of operations, these non-GAAP financial measures, when viewed individually, are not necessarily a better indicator of any trend as compared to GAAP measures such as net income (loss) or cash flow from operations. In addition, you should be aware that adverse economic and market conditions may harm our cash flow.
