Dive bar: You can swim up to cocktail service at the JW Marriott Cancun Resort & Spa, one of more than 2,500 properties participating in Marriott's 20% off promotion.

Followers of Perrin Post on Twitter have known about Marriott's Global Rate Break since Wendy informed them about it last week, but it's such a wide-reaching deal, and can help so many travelers book affordable fall getaways, that we've decided to cover it here on the blog, too.
The Deal: You get 20% off weekend stays Thursday through Sunday at more than 2,500 Marriott hotels among the company's various brands and spanning several price ranges. Included in these are a few properties ranked on Condé Nast Traveler's Gold List of readers' favorite places to stay, including the JW Marriott Cancun Resort & Spa, where you'll pay $223 a night for an ocean-view guest room, down from the standard $279 a night for the same room (all rates include fees and taxes).
The Dates: Book by September 24 for travel between September 25 and December 13.
How to Book: Log onto Marriott's Global Rate Break page, which is preloaded to make resevations with the promotional code F5X. Enter the destination you'd like to travel to and your preferred dates and hit the "find" button to locate properties in the area that are participating in the promotion and that have availability.
Caveat: Although the Global Rate Break generally trumps Marriott's other promotional rates, we noticed that for some properties, playing around with dates and with and without the promo code can yield an even bigger price break. For example, when testing for the dates of Thursday, October 1 through Monday, October 4 at the JW Marriott Cancun Resort & Spa, I was able to find an ocean-view guest room for $212 a night--or 24% off the standard rate--through the promotion code-less "Advance Reservation Rate."
Technical Note: The Global Rate Break page displays better on Safari than on Firefox. If you experience trouble viewing the Marriott Web site's booking program, try a different Web browser.
