You are probably wise in not planning to dive as Jamaica is not a dive destination! There may be some nice place’s to dive but finding a dependable opp is very difficult! I went to extreme effort to find the best in Negril after finding a opp with good reviews very hard to find that in itself. Comitted to dive with them supposedly 4 other divers going? When I was picked up only one diver going and he was in training doubtfull we would go to a location that I was hopeful for. The other diver was a no show and they offered me a beach dive that I declined since I probably seen better snorkeling on our sunset cruise to a reef, caves and snorkeling the caves at our cottage. The only dependable diving is probably at the large resorts for the newbe diver. We had a wonderful time since diving was not the main plan for the trip!
