DSis and I were at POFQ from 9/01 - 9/09 and the only place we saw anything about this promotion was on the resort TV channel in our room. In the dining segment, the first thing that popped up was the bounceback offer with instructions to call 8844 before checkout.
Even though we were aware of the bounceback, we did not book it. We had
free dining last year, and we could have had it this year, too, but opted instead for the great AP rate for our room and mostly counter service meals instead, which saved us quite a bit.
The two main reasons we didn't book the bounceback during our stay this year was when we had free dining last year, we ate way too much (and wasted too much as well), and ADR's tied us to a strict schedule with not much opportunity for spontaniety.
Also, for us, affordability of a WDW trip is a big issue and it is more economical to book with a room discount and eat lighter meals (another plus being the lighter meals don't leave us feeling so stuffed). Don't get me wrong, most of the TS food was great and we have some real favorites, but in the future, we will likely stick with the room discounts and pick one or two TS restaurants during a stay.
