I was at the Polynesian at the same time as Goofy4Tink, and her room was one above, and one over from us. The only time we heard a noise was the night when the people in the room next to us (and under Goofy4tink) called to have something fixed in their room, and there was banging for about a half an hour. Other than that, it was quite peaceful and relaxing.
We had a great room in Tokelau, and had a water view at a garden view price. We could see the Floridian from our room as well.
We had a wonderful housekeeper, Ada, who took great care of us throughout our stay. She knew we went through a lot of towels, and she always gave us extras. If we needed anything, all's we had to do is leave Ada a note, and it was taken care of.
I found the staff to be extremely kind and helpful. We were always greeted with a warm smile, and an Aloha. The staff at Captain Cook's remembered us when we went there to get breakfast each morning.
The only problem we had with transportation was when we were trying to get to Blizzard Beach one morning. We waited about a half hour for the bus, and others had been waiting fifteen minutes before that. Other than that, the transporation was great.
Try not to worry. Just go, and let the magic take you away. It may be a nice change of pace for you!
