Just to comment I dove with Big Blue diving and got a terrific deal... 500 baht for a very comfortable private a/c suite as long as I dove that day and 900 baht/dive including ALL equipment Phenomenal, I am pleased! Infact, they offer FREE dorm accomodation if you dive there which I think is a ridiculously good deal..I have never heard of such a deal before. Staff at Big Blue were super, had a great time!
