Got back last week from a weeks stay at Poly. My first time to that particular resort. Although I found the grounds to be stunning, and the views of the lake and MK to be great (as well as the atmosphere in general), I probably won't stay there again.
1) It is too spread out! I know this is part of the atmosphere, but the only thing less than a 15 min walk was the quiet pool (we stayed in Rapa Nui sp?) and we only went there twice for about an hour. The walk to the TTC or the resort's monorail was about the same, but since you have the transfer to go to Epcot, we usually just walked to the TTC.
2) Although the rooms are refurbished, they are still simply not worth the cost. The sheets were stained and had holes in them (and the beds were not very comfortable), the ceiling fan did not work, there were was no air vent or exhaust in the bathroom (which means you are sweating when you get out of the shower. The refurb seemed like little more than a fresh coat of paint and a new TV.
We had a great time, and the Poly was lovely, but on our next trip, I think we might shoot for the more compact Cont or GF. Or maybe even the Swan/Dolphin or Boardwalk, which are closer to our favorite two parks - MGM and Epcot. I stayed at the Swan in 97 and it was great. I haven't stayed at the Cont since I was a kid and never at the GF, but everything seems much closer and I understand both have rooms that are in a little better shape.
Just me two cents!
