Over all.. Terrible..
The boat ride there is not a catamaran, it's a small very poorly build boat.
Once you get to the island (about 20 mins), the beach is incredibly dirty- cigarette butts and garbage everywhere. The shore is filled with rocks, as well as the beach, so swimming isn't really an option.
The banana boat ride was less than 2 mins and you could only go once. And the kayaking/snorkelling.. You were given the tools but expected to find your own spot on your own and know what to do.
The food was the only decent thing- extremely salty Marlin fajitas.

Long story short, don't waste your money on this excursion.

Not worth the money (approx. $125 for 2 adults and 1 child) for approx. 5 hours. We slow motored to the island for an hour and then we only got to ride the banana boat once, the kayak once and snorkel once for about 15 minutes. And the food was not good - sliced Marlin stew (for tortillas), rice and beans. And since we were staying in an All-Inclusive resort, the free drinks didn't matter to us. When we returned to the hotel, everyone on our tour from our hotel went straight to the hotel buffet. So......I would not recommend.

Activities include Banana Boat rides, snorkling if the weather cooperates and horse back rides-did not see this. Lunch is on the beach-around 1 pm-wraps with warm meats and vegetables and fried beans -not wonderful-OK-all drinks on the island are included as well as drinks on the catamaran. Sounds like the Stone Island tour has better barbecue lunch.

I went with my 3 x 30 somethings 1 infant, 1 x 60 something

Positives:
Boat ride was cool, it took you to the local islands to see them, it was about and hour or hour and a half. The beach was secluded, no vendors harassing you, and it was quiet. All you can eat and drink included on the tour and the tour guides we had (Aries Fleet) were nice and helpful

Negatives:
The beach had a lot of shells and actually wasn't as clear as the beach by our resort. All you can eat and drink is great but we had that at our resort anyways. Snorkeling wasn't very clear as the water was murky, didn't really see any fish.

I'd recommend this tour if you're not already staying at a resort and maybe just staying in town or a condo somewhere in which you're not at the beach/pool all day and don't have all included food/drinks. If you're already staying at a resort where you're getting all this, I'd say you could probably save the $50.
