cti is in ochi, ricks in negril you are looking at 2.5-3.5 hour drive EACH way. I would hold off on ricks until you visit a negril property. Cool place but certainly not worth the 6-7 hours in a car. Most folks who stay in negril go for 2-3 hours tops, as soon as the sunsets the place empties.
Rick's Cafe is in the West End of Negril. It would take you 3 to 4 hours each way bay taxi cab. You could fly using TIMAIR and cut your time to 30 minutes, but that would cost $800 to $900 round trip for two.
