I stayed at a courtyard in Tampa on a last minute booking just last weekend and the 2K bonus rate was actually less than the regular rate so i booked it ( i belive adv purchase had just closed probably by a day or so before I made my booking ). Initially the stay posted without the bonus 2k so I was going to call but didn't get time to do so and then I noticed today the 2k bonus showed up in a separate account item.

I think it is a good deal if paying $10 or so above the advance purchase rate for 2k, especially if it is flexible? It does seem that you receive different "deals & packages" rates if you search when logged in versus not, maybe some rates are just reserved for platinum or whatnot as I have seen some bonus rates with titles of "special rate for elite members."
