We last stayed at Poly so that's what I voted. We stayed there because there was a great rate on GV rooms last summer and for 2 nights it didn't hurt the wallet too much. I also always wanted to stay there. We liked it, but I wouldn't say we loved it. We've also stayed at Pop and CSR -- liked both of those resorts too -- they're all great for different reasons. We plan on trying a new resort every time we visit WDW. The only trip we had huge resort regret over was our offsite trip -- any on site resort would have been better.
Next up is a toss between POR/POFQ, AKL, or WL. The 3 lowest on our list would have to be the All Stars, CBR, and the Contemporary.
