Best Mayan ruins, scuba, beach excursion for western Caribbean cruise

[Farley5]

We will be going to Belize, Routan, and cozamel. We have three kids. With different ages and adventure level so we may split up. Which port best for Mayan ruins? Which is best for scuba and what is an alternate option for non-scuba divers. Best scuba company? Or use ship excursion. What would you definitely wouldn't want to miss. Is hiring a driver the best way to get around and at which port? Kids are 10 less adventurous, 18 most adventurous and certified diver, 21 medium adventurous

Thanks for the help
