I like this property. At the time I stayed there, I was a Gold and was upgraded to a top floor suite with a Disney view. My little kids loved watching the fireworks from the room.
It is a fairly typical atrium-style ES. It shares a parking lot with the HGI and the Hampton Inn. Parking was free in the summer of 2005, despite the website indicating that a fee would apply. It does cater to Disney, meaning lots of kids, but given that I was there for the same reason, it didn't bother me.
The trolley to Disney was pretty good, not great. I did walk to the parks a couple of times -- it's a long way but certainly walkable if the weather is nice.
