Ok so your going to Hatti, Cozumel, Jamacia and Grand camon? We went on the Explorer last year and to the west carribean. I sugggest in Jamacia to go to Dunns rivers falls-And be ready for a roller coaster ride if you take a taxi/van! In Cozumel I also suggest Chankaab Beach! It's only about a 10 minute ride from the port. And at Labadee/Hatti-If you have children-The beach right next to the port is fantastic. Kids always enjoy the trampolines in the water!!
