Explanatory Note

Marriott International, Inc. is filing this Amendment No. 1 (the “Form 10-Q/A”) to our Quarterly Report on Form 10-Q for the quarter ended March 26, 2010 (the “Form 10-Q”), filed with the Securities and Exchange Commission (“SEC”) on April 23, 2010, for the sole purpose of correcting the Interactive Data File furnished as Exhibit 101. The previously furnished Interactive Data File showed that in our Document and Entity Information, the share count as of April 9, 2010 was 361,332,043 shares of Class A Common Stock and that this share data was “in millions.” However, this data was in actual shares and we have deleted the “in millions” from our Document and Entity Information in our Exhibit 101 to this Form 10-Q/A.

No other changes have been made to the Form 10-Q. This Form 10-Q/A continues to speak as of the original filing date of the Form 10-Q, does not reflect events that may have occurred subsequent to the original filing date, and does not modify or update any related disclosures made in the Form 10-Q.
