We have so many favorites (all of them!). One that is great for families of 6 is the Courtyard Waterpark and Theme Park Entrance. It has spacious rooms, large bathroom, with 2 showers, 2 queen beds, bunk bed, and of course a WATER PARK.
The Tropicana Hotel is directly across the street, they recently had a renovation that has made all the difference of their hotel. The Tropicana is fresh, colorful, and clean. We love going to the Tropicana Hotel, we always feel comfortable and well taken care of by the staff.
