                           Registration Statement on Form S-3

Ladies and Gentlemen:

                  We have served as Maryland counsel to Starwood Hotels &
Resorts, a Maryland real estate investment trust (the "Trust"), and Starwood
Hotels & Resorts Worldwide, Inc., a Maryland corporation (the "Corporation," and
together with the Trust, sometimes collectively referred to herein as
"Starwood"), in connection with certain matters of Maryland law arising out of
Starwoods's registration statements on Form S-3 (Nos. 333-40077 and 333-40077-1)
and all amendments thereto (collectively, the "Registration Statement"),
previously declared effective by the Securities and Exchange Commission (the
"Commission") under the Securities Act of 1933, as amended (the "1933 Act"),
relating to the proposed public offering of securities of Starwood that may be
offered and sold by Starwood from time to time as set forth in the Prospectus,
dated on or about the date hereof, which forms a part of the Registration
Statement (the "Base Prospectus"). This opinion is rendered in connection with
the registration, sale and issuance of up to 5,827,975 shares (the "Corporation
Shares") of common stock, par value $.01 per share (the "Common Stock"), of the
Corporation and up to 5,827,975 shares (the "Trust Shares") of Class B Shares of
beneficial interest, par value $.01 per share (the "Common Shares"), of the
Trust, each of which is attached to a Corporation Share and trades as a unit
consisting of one Corporation Share and one Trust Share (the "Shares"), issuable
upon

                  16. Such other documents and matters as we have deemed
necessary or appropriate to express the opinion set forth in this letter,
subject to the assumptions, limitations and qualifications stated herein.

                  In expressing the opinion set forth below, we have assumed the
following:

                  1. Each individual executing any of the Documents, whether on
behalf of such individual or any other person, is legally competent to do so.

                  2. Each individual executing any of the Documents on behalf of
a party (other than Starwood) is duly authorized to do so.

                  3. Each of the parties (other than Starwood) executing any of
the Documents has duly and validly executed and delivered each of the Documents
to which such party is a signatory, and such party's obligations set forth
therein are legal, valid and binding and are enforceable in accordance with all
stated terms.

                  4. Any Documents submitted to us as originals are authentic.
The form and content of any Documents submitted to us as unexecuted drafts do
not differ in any respect relevant to this opinion from the form and content of
such Documents as executed and delivered. Any Documents submitted to us as
certified or photostatic copies conform to the original documents. All
signatures on all Documents are genuine. All public records reviewed or relied
upon by us or on our behalf are true and complete. All statements and
information contained in the Documents are true and complete. There has been no
oral or written modification of or

amendment to any of the Documents, and there has been no waiver of any provision
of any of the Documents, by action or omission of the parties or otherwise.

                  5. None of the Shares will be issued, sold or transferred in
violation of the Charter, the Declaration or the Intercompany Agreement.

                  6. Upon issuance of the Shares, the total number of shares of
Common Stock issued and outstanding will not exceed the total number of shares
of Common Stock that the Corporation is then authorized to issue under the
Charter and the total number of Common Shares issued and outstanding will not
exceed the total number of Common Shares that the Trust is then authorized to
issue under the Declaration.

                  The phrase "known to us" is limited to the actual knowledge,
without independent inquiry, of the lawyers at our firm who have performed legal
services in connection with the issuance of this opinion.

                  Based upon the foregoing, and subject to the assumptions,
limitations and qualifications stated herein, it is our opinion that:

                  1. The Trust is a real estate investment trust duly formed and
existing under and by virtue of the laws of the State of Maryland and is in good
standing with the SDAT.

                  2. The Corporation is a corporation duly incorporated and
existing under and by virtue of the laws of the State of Maryland and is in good
standing with the SDAT.

                  3. The Shares have been duly authorized by all necessary
corporate action on the part of the Corporation and trust action on the part of
the Trust and, when issued and delivered by the Corporation and the Trust upon
conversion of the Notes and in accordance with the terms thereof, will be
validly issued, fully paid and non-assessable.

                  4. The issuance of the Notes has been duly authorized by all
necessary corporate action on the part of the Corporation.

                  5. The Corporation has the corporate power to execute, deliver
and perform its obligations under the Notes and the Indenture.

                  6. The Trust has the trust power to execute, deliver and
perform its obligations under the Indenture.

                  7. The Notes have been duly authorized, executed and, so far
as is known to us, delivered by the Corporation.

                  8. The Indenture has been duly authorized, executed and, so
far as is known to us, delivered by the Corporation and the Trust.

                  9. The execution, delivery and performance by the Corporation
of each of the Indenture and the Notes do not and will not violate the Charter
or the Corporate Bylaws.

                  10. The execution, delivery and performance by the Trust of
the Indenture do not and will not violate the Declaration or the Trust Bylaws.

                  The foregoing opinion is limited to the substantive laws of
the State of Maryland and we do not express any opinion herein concerning any
other law. We express no opinion as to the applicability or effect of any
federal or state securities laws, including the securities laws of the State of
Maryland, any federal or state laws regarding fraudulent transfers or any real
estate syndication laws of the State of Maryland. To the extent that any matter
as to which our opinion is expressed herein would be governed by any
jurisdiction other than the State of Maryland, we do not express any opinion on
such matter.

                  We assume no obligation to supplement this opinion if any
applicable law changes after the date hereof or if we become aware of any fact
that might change the opinion expressed herein after the date hereof.

                  This opinion is being furnished to you solely for submission
to the Securities and Exchange Commission as an exhibit to the Registration
Statement. We hereby consent to the filing of this opinion as an exhibit to the
Registration Statement and to the use of the name of our firm therein. In giving
this consent, we do not admit that we are within the category of persons whose
consent is required by Section 7 of the Act.

                                      Very truly yours,
