my friend and I did Isla Passion by Catamaran in Cozumel. It was a pleasant boat ride to and from, nice beach with lounger plus open bar, food buffet included.
We had stingray experience scheduled for Grand Cayman but we were able to cancel the day of because there was a storm coming and the ship couldn’t dock in its normal spot. We had table mates that did it. Spent 2 hours on a bus since we weren’t parked by Georgetown.
