I have always taken my cell phone and my room key with charging privileges to the pool. When I leave my area, I cover my Passporter pouch with my towels and coverups. I have never had a problem. However, I always think about it and it does make me nervous. If it is going to bother you, I would buy a waterproof case and wear it while you swim. Sometimes if I know I won't be charging anything, I take my dd's room key that does not have charging privileges and that way, I don't worry about it.
