Yeah, Florida's so much fun, hard water & high humidity/dews, yay!!!
Maybe try a final rinse with distilled water? I am also finding a hard hold gel to be a big help, did you bring one with you?
I'm fairly new to the CG thing, I've always just put my hair in a braid, bun or other containing/taming style when it goes poofy. You're on vacation, put it up or tie it back and enjoy yourself!
