I did not do this tour however my husband and son did. I set it up online for them before we arrived in Cozumel. They are great communicators on email and they picked the boys up from the pier at our resort– The Occidental Grande. I did not want to dive but they invited me on the boat which I thought was cool. I had a good book and wanted to relax on the beautiful beach with a margarita instead. The boat hung out near the pier as they gave through information about diving to the boys. Then they had practice time in the shallow water before the 2 tank discovery dive. They said Israel was super nice, friendly and informative. They felt safe and in good hands. They were gone for hours. When they came back they were both excited to tell me all about the dive and everything they saw. They saw sea turtles, lots of schools of fish, Barracudas and my husband saw the largest Eel ever!!! They ranked this tour 5 stars and said the guide was great and very informative about diving. They thought the Captain was super nice and friendly. This excursion made their trip and they enjoyed this adventure in the sea 100%. One tip bring an underwater camera like a GoPro– I enjoyed seeing all the pictures!
