Well, for me, I remember wearing my rashguard last year on Ihu's, but it is a looooong way up for me to have to walk all the way down, so I might reconsider for September. Reading between the lines, it is a matter of which lifeguard is at the top, which is my #1 biggest complaint of ANY waterpark, and I have been to many. Same rules, all the time, everyone! Ugh...
