The towels do need to be signed out and back in - AND they are only available at the main pool - not at the quiet pool/hot tub. If you are heading over to that area you need to stop by the Mickey shaped pool first and get your towels - and return them there. The towels were adequate, and there were plenty available.

Last August we was able to get towels and no signing out. I actually wore one around my waist on my walk back to my room. Maybe thats why you have to sign them out. I would hope not.
