Be prepared to be OVERWHELMED! This is the largest hotel EVER!!! HUUUUGE!!
We stayed there on a Priceline bid a few years ago and just LOVED it. It has about 6 or 7 pools and we were there with my son and his babysitter who just adopted a little girl. The little girl, 7, told us she felt like she was in HEAVEN!
The kids loved the glass elevator, I swear they thought it was a RIDE, and just to ride it and see the skyline is a sight to behold!
Don't miss Champions, the sportsbar on the first level. My son and I went back there last month again because the food is so good even though we were staying at the Grande Vista.
It's mostly a convention hotel so be prepared for that, lots of executive types running around, not Disney themed. A class act nonetheless and very close to Disney.
Enjoy!
