We've been twice, and both times we hired a taxi to drive us all around the area for the day. We stop if something interests us, but mostly we tell her what kind of day we'd like to have and let her figure out where those things would be.
The first year we just hired a driver as we came out of the terminal in Jamaica. We got a very nice woman who took extremely good care of us. So this year, I made arrangements by email to go touring with the same driver again. She'd given us her contact information, so we had her lined up months before the cruise.
If you'd like her name and contact info, let me know.
