re: Cruise excursions

Check Trip Advisor. Look at "Top Things to Do" and click "See all" on the port's home page. Then choose " Sightseeing Tours" or "Private Tours." Do not choose anyone with less than 4 or 5 stars. Check the reviews to see if other cruise passengers have used them. Alot of private tour guides will help you build your own excursion.

You absolutely want to have an excursion planned for Jamaica. It's beautiful, but it's a rough port. A lot of hustling going on when you get off the ship. It's good to know exactly what you're going to do. Check your ship's excursions as well.

In GC, at the very least, you can grab a cab and head down to 7 mile beach. You can find private boat tours on Trip Advisor.

Hope that helps! I've done this itinerary twice and I like both ports.
