Dorm-style accomodations in Central American sites

[drbill]

I enjoy dive travel as a backpacker, living in dormitory-style accommodations so I can spend my money on the diving itself rather than a fancy room in which my eyes would be closed most of the time anyway.

I am looking for dive "resorts" and operations with nearby dorm-style accommodations at Central American locations. I plan a 2-3 month trip traveling to many different locations. Anyone have any recommendations?

TIA,

Dr. Bill
