scubawife:Thanks everyone for the info. Have any of you stored your gear at the lockers when you were not diving with Dive House? I hadn't planned on using them. If it's worthwhile, I'd like to do a shore dive in the afternoons so we would rent a tank for that. If we do shore dive in the afternoon then we will need to keep our gear rather then have the op we use store it overnight. That's what made the casita appealing - it has it's own locker.
BTW, any comments on the shore diving out in front of FA?
With the number of lockers that Dive House has available, I doubt they would let anyone other than their own customers use them. Maybe if you slip them a few pesos

Shore diving out in front of the FA isn't worth the nitrogen absorbtion in my opinion. It's good for checking out your weighting prior to jumping off of a boat, but that's about it. The snorkeling isn't half bad though.
