radisson resort parkway has a nice slide-not as big as beach club or boardwalk but bigger than the one at port orleans riverside. We stayed there years ago and enjoyed it .There is also a waterfall in the pool. Caribe Royale is another place with a nice pool and waterfall, I did not stay there but have friends who did and enjoyed it as well. Both hotels are located close to disney and both have websites with pictures of the pools. Caribe Royale can accomodate 6 people in a room if you need to, they have a separate bedroom.
