I know this has been asked before but I really did do a search and couldn't find anything. We leave this evening for our trip and I am just out of room in the suitcases. Do we really need to take our beach towels to the waterparks? Can't we just take one from the hotel? I know you can rent them at the water parks but I am not going to do that. Has anyone ever just borrowed one from their room and used it?
