They go south and dive of course.
The choice this time was a dutch owned island named Bonaire. Part of the commonly referred to as the ABC islands together with Aruba and Curacao. It is famous for its donkey sanctuary, flamingos and its diving.
You can dive on your own schedule. You can dive alot or a little. The choice is yours. Anyone who has experienced "unpleasant" co-divers on dive boats can really appreciate this style of vacation.
