They have options for divers who come with their (non-diving) family - the kids can go snorkeling while the parents dive. The pick up is personalized, so you don't spend >1h extra in a bus waiting for all the pick ups from all the hotels. Also you get most of the information already on the way, so the time is optimized.
The dive sites are _way_ better on the Caribbean side, just forget the hassle and do not even try diving in the Atlantic...
They also do all kind of courses, from very beginners (discover scuba from the age of 10) to all level.
Also they prepare all your dive gear prior to your arrival, so you don't have to carry heavy stuff. You really feel cherished and can fully enjoy holiday dives.
Lise makes happen everything you could just ever dream of! And her joyful and professional crew takes care of everything.
