In a word, sandals.
Unlimited diving included, which translates to 3 to 4 dives a day depending on the resort.
All equipment supplied. With Butler service they will even take your gear to the boat.
For all the sandals deniers, yes the dives can be shallow conservative and boring. But the certified diver morning dives can be more challenging deeper dives. Some in Jamaica are 100 foot wall dives. Available dives are listed by resort on the Web site. Some resorts offer additional pay for dives like night and shark dives.
Lots of stuff to keep the non diving spouse busy while you’re gone.
