...on a another note: I just got my kids certified. (kids... 21 and 23 years old) and hope to put together a dive vacation for their first experience. I'm thinking some place easy diving. Florida keys, Roatan, and alike...again, thanks for all the info you give. really helpful.
The Caymans are a great place for an easy diving experience. Grand Cayman also offers non-diving activities that might be of interest to young adults.
Or you might consider one of the small, diver-dedicated, all-inclusive resorts on the sister islands like Cayman Brac Beach Resort or Little Cayman Beach Resort.
