Took my son to Comanche Nation Water Park last Sunday..had a lot of fun.

BUT...be careful if you order from the snack bar place and use a debit card. It charges you $1.25 just for using your card. I ordered a chimichanga for $2.00 she said my total was $2.10, gave her my card, and then I was looking at my reciept it said total $3.41 or something. NOT COOL. So if you can, USE CASH. :) 

I'll have to keep that in mind if we go. How late are they open? Also, I wonder what day they close for the summer. We won't be there till around mid-August, so I wonder if they will still be open.
