Sounds interesting - but I've always wondered how's the safety of your stuff/gear at backpacker/uber-cheap accommodations?
With luck you find a room with an outside padlock - bring your own & your stuff is pretty safe. Just in case make sure to have $6 shore diving is $7 a tank with your own gear $15 with horrible rental gear & a guide. It's great and relaxed diving!
Have fun, I'll be there in a few months ! Don't take my room!!! Just kidding!
