Went to CTI for 3 nights 4 days. Was a great trip! The only problem we had was we didn't stay long enough! Make sur eyou book the specialty restraunts in advance. They do allow that over the phone prior to travel (they indicated when we booked it wasn't allowed and when we showed up they were all booked). Very accomodating with us, even caught some fish and brought it back to the resort. The chef prepared it and cooked it for us for an afternoon snack!
Try the Jamaican Smile drink. It is great! Skip the catamaran cruis, not that good. Do go snorkeling and scuba diving- both great trips! There is also a guy named Michael that sells nice shells and conch. He paddles up to the resort on a surf board. He can arrange a low cost deep sea fishing trip for you. Good times at CTI.
