belize, roatan and cozumel excursion recommendations please

We are an active family of four (2 teenage boys). From my research so far, its appears that the best snorkeling is at Tabyana in Roatan and best ziplining in Belize.

Should we just take a taxi from the port to Tabyana and spend the day snorkeling and hanging on the beach? Any other ideas?

In Belize, do ziplining and/or ziplining and cave tubing? What company do you recommend booking with?

Ruins in Cozumel or any other ideas welcome. Thank you!

We just got back...

We did Amazing Race in Cozumel and it was great.

In Belize we did the caves, probably not exciting enough for your boys. The float s so slow they had to pull us along. It was fun and neat to see, but not exciting by any means.

I have a list of things in my signature line that you are welcome to read (they have TONS of pictures) and see if any interest you. :)

I am interested if anyone can went to Tabayana Beach privately and not through Carnival. I would like to spend the day there snorkeling and not on a Carnival excursion
