It's been a couple years since I've been there, but have dove with both Couples resorts in Negril, and also with Sundivers. Sundivers has a website, Sundivers.com, you can book before your trip, reasonable rates and they pick you up at your hotel, if you are near there. Dove with Marshall, very good divemaster, had a good time there. Nobody is in a hurry on Jamaica, seems like everything is about 15 minutes late. Plenty of good dive sites on Jamaica, but you don't see big fish there like you do on Cozumel. One time I met a grouper at Coz bigger than me. Jim
