When i was on a Carnival Cruise last summer I did horseback riding along a beach in Jamaica. It was a blast, at the end of the ride we were on a beach, the wranglers or whoever you want to call the people who led us on the ride, took off the horses sadles and we rode bare back in the ocean. This was soo fun, the horses went out into the water untill it came up to the tops of their back so it was like you were just gliding along the top of the ocean it was sooooo fun. So it you do get a chance to ride, see if they have any rides that will take you into the water, it is something i will allways remember.
