The hotel was technically clean but needs work. The rooms need updating. The water park needs work. There is a lot of rust on the metal fixtures in the water park. The towels in the water park are nothing more than very thin hand towels.

The resort is average as far as cleanliness and rooms go. I appreciate the location convenience, the riverfront path and view, Tony Romas, and the water park when grandkids are with us. Parking is convenient and the staff is always friendly and helpful.

Each employee I encountered was most helpful, kind and efficient. I had a dead battery and Diane (?) and Pierre (?) didn't hesitate to help me. Brad, in the arts/crafts kids room was AMAZING! My granddaughters just loved him. They colored a picture for him. My grandson totally enjoyed the arcade. And, of course, the waterpark was perfect! It was well tended by staff. The gal, at the concession, was so good. She managed everyone with quick service, a smile and good attitude. I've been telling everyone about our experience. We WILL be back!!
