Good morning Ricky, the answer is at least 10 and you will need to book in advance at least 24 hours. The discount would be 5% so on a 48" or taller person the price would be $36.09 + tax instead of $39.99 + tax. There is a hotel package which included hotel room and entry to water park the evening you check in and the whole next day. If you are interested in the hotel package you can call directly to the Holiday Inn Express next door at 580-323-1950. If you want to arrange for a group without hotel, you can call the water park at 580-323-9966. Carolyn Schumacher, CFO
