We're heading down to Bonaire in a few weeks and my youngest (9) has expressed strong interest in some sort of "intro to SCUBA" while my middle daughter (12) has expressed what we'll call "tepid" interest. What options should I consider and are there any particularly good operators/organizations in Bonaire that could expose the kids to SCUBA safely? Rest of family (mom, dad, and oldest son) are already certified so this would be some good early exposure and hopefully steps towards my not-so-secret plan to create a family of divers.
