Advice needed on "Caves, Caverns and Paradise Lagoon" excursion in Cozumel

[Shel71]

I am looking to hear from others who have done the Caves, Caverns and Paradise Lagoon excursion in Cozumel. My family, DH, myself, Ds (16) and DD (14) all want to book this excursion. My youngest DS (11) doesn't like to snorkel. I had thought about the Fury Catamaran Sail Snorkel and Beach Party instead so that my youngest could just watch from the boat, but everyone really wants to do the Caves excursion.

 

From those of you that have gone on this excursion would it be possible for my youngest DS to watch from the sidelines or do you move from one place to another through the water meaning you must get in the water to attend?

 

Obviously I would pay the full fare, it's not about $$, I just want everyone to get to do what they are happy and comfortable with.

 

We are sailing on the Disney Fantasy, but I am guessing other cruise lines do similar excursions as well?

 

Any insight from those in the know is much appreciated!
