I would give the guy a 5, but his van broke down on the return to the port and we were 30 minutes away from missing the last tender. I was very happy with the tour and our entire family LOVED the cave tubing. Highly recommend.
We liked snorkeling. Our tour guide took us to 3 different spots. It was fun, except at one of the locations there were tons of jellyfish and we all got stung about 20 times! These little jellyfish were like bees stinging us. We negotiated $100 for 3 of us, included beer, water and soda.
