CUSIP No. 25272T104 13D/A Page 6 of 8 Pages

This Amendment No. 3 to Schedule 13D (this “Amendment No. 3”) relates to the common stock, par value $0.01 per share (the “Common Stock”), of Diamond Resorts International, Inc. (the “Issuer”), and amends the Schedule 13D filed by Chautauqua Management LLC, Chautauqua IIA, LLC, Chautauqua IIB, LLC and David F. Palmer (collectively, the “Reporting Persons”) with the Securities and Exchange Commission on August 5, 2013, as amended by Amendment No. 1 to such Schedule 13D filed on August 18, 2014, and as further amended by Amendment No. 2 to such Schedule 13D filed on September 11, 2014 (as so amended, the “Schedule 13D”). The address of the principal executive offices of the Issuer is 10600 West Charleston Boulevard, Las Vegas, Nevada 89135.

This Amendment No. 3 is being filed by the Reporting Persons to furnish the additional information set forth herein. Except as specifically provided herein, this Amendment No. 3 does not modify any of the information previously reported in the Schedule 13D. Capitalized terms used but not defined herein shall have the meanings ascribed to them in the Schedule 13D.

Item 4. Purpose of Transaction.

Item 4 of the Schedule 13D is hereby amended by adding the following:

On July 11, 2016, 1818 Partners distributed to each of its members, including CML, a portion of each of the DRPH Call Option and the Silver Rock Call Option with respect to one-third of the shares of Common Stock issuable upon exercise thereof (i.e., an aggregate of 1,511,808 shares of Common Stock issuable upon exercise of the DRPH Call Option, and an aggregate of 143,958 shares of Common Stock issuable upon exercise of the Silver Rock Call Option). The distribution by 1818 Partners to its members was made pro rata, based upon the members’ respective equity interests held in 1818 Partners. Each of CML and the other members of 1818 Partners assumed the terms and conditions of the DRPH Call Option and the Silver Rock Call Option with respect to the portion thereof so-distributed to such member pursuant to separate transfer agreements. In connection with the distribution, CML entered into separate instruments, dated as of July 11, 2016, representing the portions of the DRPH Call Option and the Silver Rock Call Option, respectively, distributed to it.

The distribution by 1818 Partners had the effect of reducing the number of shares beneficially owned by CML and Mr. Palmer, because each of CML and Mr. Palmer previously reported shared beneficial ownership of all of the securities underlying the Call Options, indirectly through 1818 Partners, even though CML and Mr. Palmer only had a one-third economic interest in the Call Options. The distribution by 1818 Partners to its members did not effect any change in the pecuniary interest of CML or Mr. Palmer in the Call Options.

In connection with the distribution of the Call Options, Cloobeck Companies, LLC, an entity owned and controlled by Stephen J. Cloobeck and a member of 1818 Partners that received a portion of the Call Options pursuant to such distribution, became a party to the Stockholders Agreement. The distribution by 1818 Partners did not change the aggregate number of shares covered by the Stockholders Agreement.

On July 15, 2016, CML exercised in full the portion of the DRPH Call Option distributed to it (the “Distributed DRPH Call Option”) for an exercise price of $12.56 per share. CML exercised the Distributed DRPH Call Option pursuant to the “cashless exercise” provision thereof, resulting in DR Holdco, LLC withholding an aggregate of 630,004 of the shares of Common Stock underlying the Distributed DRPH Call Option to pay the aggregate exercise price of $18,988,308 and issuing to CML the remaining 881,804 shares. On July 19, 2016, CML also exercised in full the portion of the Silver Rock Call Option distributed to it for an exercise price of $12.56 per share, and CML acquired an aggregate of 143,958 shares of Common Stock in exchange for an aggregate cash exercise price equal to $1,808,112.

CUSIP No. 25272T104 13D/A Page 7 of 8 Pages

On June 29, 2016, the Issuer announced that it entered into an Agreement and Plan of Merger (the “Merger Agreement”) with Dakota Parent, Inc., a Delaware corporation (“Parent”), and Dakota Merger Sub, Inc., a Delaware corporation and a wholly owned subsidiary of Parent (“Merger Sub”), providing for the acquisition of the Issuer by Parent in a two-step all cash transaction, consisting of a tender offer (the “Offer”), followed by a subsequent back-end merger of Merger Sub with and into the Issuer (the “Merger”), with the Issuer surviving the Merger as a wholly owned subsidiary of Parent. In connection with the Offer, on July 14, 2016, the Issuer filed a Schedule 14D-9 with the Securities and Exchange Commission. As reflected in the Schedule 14D-9, the Reporting Persons currently intend to tender, or cause to be tendered, all shares of Common Stock held of record or beneficially by the Reporting Persons pursuant to the Offer.

Item 5. Interest in Securities of the Issuer.

Items 5(a), (b), (c) and (d) of the Schedule 13D are hereby amended and restated as follows:

(a) The Reporting Persons may be deemed to beneficially own 6,406,704 shares of Common Stock, representing approximately 9.00% of the Issuer’s outstanding Common Stock (based on 69,745,698 shares of Common Stock outstanding).

(b) Mr. Palmer has sole voting power and sole dispositive power with regard to (i) 1,473,850 shares of Common Stock underlying options held by him, and (ii) 3,699,560 shares of Common Stock held by CML, of which Mr. Palmer is the sole manager, and (iii) 616,647 shares of Common Stock held by CIIA, of which he is the investment manager. Mr. Palmer may be deemed to have shared voting power and shared dispositive power with regard to 616,647 shares of Common Stock held by CIIB, of which Mr. Palmer’s spouse is the investment manager. CML has sole voting power and sole dispositive power with regard to 3,699,560 shares of Common Stock. CIIA has sole voting power and sole dispositive power with regard to 616,647 shares of Common Stock held by it. CIIB has sole voting power and sole dispositive power with regard to 616,647 shares of Common Stock held by it.

The share ownership reported for the Reporting Persons does not include any shares of Common Stock owned by the other parties to the Stockholders Agreement, as amended by the First Amendment. Each of the Reporting Persons is deemed to be a member of a “group” for purposes of the Exchange Act with the other parties to the Stockholders Agreement, as amended by the First Amendment. Each of the Reporting Persons disclaims beneficial ownership of any shares of Common Stock owned by the other parties to the Stockholders Agreement, as amended by the First Amendment, except to the extent disclosed in this Schedule 13D.

(c) No transactions in the Common Stock have been effected by any of the Reporting Persons within the past 60 days, except as disclosed under Item 4 of this Amendment No. 3, all of which disclosures are incorporated herein by reference.

Item 6. Contracts, Arrangements, Understandings or Relationships with Respect to Securities of the Issuer.

Item 6 of the Schedule 13D is hereby amended by adding the following:

The response set forth in Item 4 of this Amendment No. 3 is hereby incorporated by reference.

Re: Transfer of Call Option Agreement with DRP Holdco, LLC

Reference is hereby made to that certain Call Option Agreement, effective as of July 21, 2011 (as amended, restated, supplemented or otherwise modified and in effect from time to time, and including all rights, claims and remedies with respect thereto, the “Call Option”), by and among 1818 Partners, LLC, a Nevada limited liability company (“Transferor”), DRP Holdco, LLC, a Delaware limited liability company (“Unitholder”), solely for the purposes of Sections 4(b) and 8 thereof, the Equityholders named therein, and, solely for the purposes set forth in Sections 7, 8 and 9 thereof, Diamond Resorts International, Inc., as successor-in-interest to Diamond Resorts Parent, LLC (the “Company”).

Accordingly, in consideration of the foregoing, and other good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, Transferor and Transferee agree as follows:

1. Transfer of Securities. Effective as of the close of business on the date hereof (the “Effective Time”), Transferor hereby transfers and assigns to Transferee, and Transferee hereby acquires from Transferor, a portion of the Call Option with respect to one-third (1/3) of the equity interests in the Company subject to the Call Option (i.e., 1,511,808 shares of common stock of the Company (“Common Stock”)), including all of Transferor’s right, title and interest, legal and equitable, therein and thereto, and all obligations of Transferor thereunder with respect to such portion of the Call Option so-transferred (the “Transferred Call Option”). In connection therewith, Transferee hereby assumes, and agrees to be bound by the provisions of the Call Option with respect to, the Transferred Call Option.

2. Further Assurances and Agreements.

Without limiting the generality of anything set forth herein, (a) Transferor and Transferee shall notify Unitholder of Transferor’s transfer of the Transferred Call Option to Transferee and Transferor’s assignment of rights under, and Transferee’s assumption of obligations under, the Transferred Call Option; and (b) Transferor and Transferee shall cooperate with each other and the Other Members in seeking from Unitholder the prompt issuance of new instruments, representing the Transferred Call Option and the portions of the Call Option transferred to the Other Members pursuant to the Distribution (the “Other Member Call Options”), in the names of Transferee and the Other Members, as applicable.
