Mr Sancho's Snorkeling Tour add on?

[redxpanda]

On the official homepage, they mention a snorkeling tour that can be added onto the cost of the day. Has anyone done this? There is very little information listed about the tour. I can't find a price and searching the net has not been much help. Most sites don't even list the snorkeling as an add on, so I'm starting to wonder if it is even worth it.

 

We are looking to snorkel while in Cozumel, but need something that is good for beginners and still fun for the more advanced snorkelers. I am also quite interested in experiencing an All-Inclusive environment and I think Mr Sancho's has everything we'd be looking for otherwise.
