This place is definitely not as advertised. It is small, unkept, and more age appropriate for 3-9 year olds. The hours on the website, on the door, and listed on the hotel website are wrong. The wave pool was not working and the staff was...More

Overpriced. The water was too cold and very small water park. Not worth the entrance fee and they don’t have towels. Save your money and just go to a hotel that has a pool.
