We approached it from two different methods this last time around. My daughter wore her bathing suit with a pair of shorts. My wife put on her poncho and remained very dry. I toughed it out and stayed in my street clothes. I dried off in about three hours ( 95 degrees). The smart thing to do would be to keep a set of dry clothes in a locker, available at the entrance to the park or next to the Comic Strip Cafe $ 2.00 for an Hour ( I think ) and change in the bathroom after the rides. For shoes and Socks Popeye's and Bluto's Bilge raft barges has a storage areas in the raft the keeps things pretty dry. Here is my degree of wetness scale.
