Pass on the horseback riding, unless it's a separate excursion being offered off of the beach. The horseback riding on the beach is offered by vendors walking up and down the beach...you basically pay, get on a horse, and the horse slowly walks beside the vendor while you ride along a very busy beach. It seemed insanely boring and not at all what you would expect.
Definitely do the catamaran cruise (do it more than once if you can!)...it was one of our favorite parts of the trip. Also, had I known to do this, I would have booked dinner at the reservation only restaurants every night of our stay...Patois Patio was good, but we never really liked The Palms for dinner...Try a Bob Marley shot! ...We went on the Glass Bottom Boat tour, it was fun, and it's kinda of a scenic tour of 7 Mile Beach...
I wish I could give more advice on excursions, but unfortanetly, it rained our entire trip so we had to cancel most of our plans, including the snorkeling which we never got to do
