Sheryl's site is absolutely fantastic! Seeing the link for months on an occasional FT post, I finally decided to try it for 4 separate days in three different cities. My results:

San Diego 7/17 Monday $45 Marriott Marina
7/26 Wednesday $45 US Grant Hotel (complimentary airport shuttle)
Tampa 7/24 Monday $40 Sheraton Suites Tampa Airport (complimentary airport shuttle)
Washington DC 7/25 Tuesday $52 Wyndham Bristol

I read through the forum and planned my strategy carefully based on the information that other people had posted. And don't forget to use the Bonus Money offers! And on the Sheraton in Tampa? I received starpoints, my gold 50% bonus, and a credit towards the Free Fridays promotion, all of which was a total surprise.

Good luck, jaguar!
