I've stayed at Poly about 6 or 7 times, CS twice, GF Twice and AKL once...
Would not choose to go back to CS over one of the others... but would if I got a great deal or nothing else was available.
Would not hesitate to go back to Poly, GF, or AKL.
I love animals, so AKL is the one I can't wait to go back to.
If money was not an factor, I'd go back to GF...
Stayed at Poly so many times for a number of reasons. Back in teh 80's there weren't a ton of hotel options... recently, it's been because my mother wants to be on the monorail and my family dislikes CS and it's cheaper than GF. But don't assume that we go there by default... we really do like it there also... we're going back to WDW at the end of the month and Poly was our first choice, but I couldn't get any price breaks, so we settled for something ess expensive.
