I've stayed there before. It's not the greatest place in the world but has more advantages than disadvantages. It's very close to the parks (even though it's not actually on the property, but is basically right outside the gates.) Also, if you are staying with 3 or more people in the same room, you will have plenty of space since there are 2 rooms in one, with a seperating door, and a tv in both. They also have a pretty good all-you-can-eat breakfast every morning.
One of the disadvantages off the top of my head was the fact that the pull out couch bed wasn't very comfortable. I think the main beds weren't that great either, but it's been a couple years since I've stayed there so I can't remember for sure. There is also the minor inconveniance of not having the great Disney shuttle bus services that you would have by staying inside the property.
It's a good hotel overall though, since you have plenty of space with the double rooms and it's close to the world gates. I doubt you will have any serious complaints.
