We looked at it to book after our mini submarine tour. So we called them but they only offer a meal included in the $49...not all inclusive. If you want to snorkel, its like $20 extra...none of the watersports are included and when writing directly to Nachicocum website, they say you can just go there and it is not limited to 100 people. Hmm...we went with the Sanchos beach break deal which was much cheaper and inlcluded all you can eat from the menue as well as snorkel equipment and kayaks (cozumel-watersports.com)...just a thought
