Going to PDC for a week in July -- and staying a La Tortuga. What do most people use to keep their valuables safe and dry on the beach? Please no lectures on not bringing stuff -- I won't be taking my camera and diamonds :-) just some cash for food and drinks. Do they have mini lockers at any of the beach clubs (I've been to places with that). Or am I better off looking for a waterproof wallet? I think we will have passes to Mamitas.
