Agreed on the Rick's thing. Don't apologize! It is part of Negril and a "must see" at least once. Plus, if you like jumping from the cliffs it is one of the highest spots. My suggestion would be to start just a little further up and... with a Stripe in hand... take a walk around the grounds of the Lighthouse. It is the western most point of Jamaica and if the groundskeeper is around you can even climb to the top and step outside. No need to spend much time but it is a cool spot to start.

Have fun and congratulations on the upcoming nuptials!!!
