I stayed there last June with my son, daugher and neice. We usually stay at a Disney Resort but this was a last minute trip and I was saving money. After the first night, I called CRO to get a room in a Disney Resort--I hated Grosvenor. The lobby was beautiful, the employees friendly. However, after checking in, we had to park the car by one of the garden wings (our room was in the Tower). While walking past the garden wings, there was the most unbelievable stench of garbarge (this stench happened to be in both garden wings). I ran into a lady who said she was requesting another room because the carpet in hers was moldy. Well, I expected the worst upon entering our room. Our room was actually pretty nice. My breaking point came when I took the kids to the uneventful pool--they didn't care that it wasn't eventful but there wasn't enough magic there for me. That's when I called CRO and explained the reason for my change. They said they would check into the garbage stench as well as condition of room based on what I heard.
$40.00 per night sounds like a great deal though. If I was only sleeping and showering in the room and not expecting too much atmosphere, I'd go for it. By the way, we sat on the fire escape outside the resort and had a good view of some far-away Disney fireworks!
