SO OUTDATED. Way too expensive of a night for how outdated the rooms and water park area are. The main slide and hot tub were not open all hours of the park being open.

Good breakfast and hotel room was clean. It’s definitely outdated and worn down in the waterpark along with some of the hotel amenities considering the nightly rate you pay. The kids had fun at the waterpark and enjoyed the games that were lead by staff.

Hotel was clean and staff were great! Quick check in! The waterpark was great and our children (2, 4, & 11) loved it! There are spots of the waterpark that could use come work as I would say the equipment is showing its age but the water was warm, staff were awesome, plenty of towels, maybe could use a little more seating/tables. Great stay and experience, would for sure go back again!
