Be mindful it's customary to tip on boat dives, including in Bonaire, whereas with shore dives that's usually not an issue. Over a week, that can rack up some cost. I'm not knocking boat diving, just saying that it will impact your budget, so be aware.

P.S.: This may be a bit much to get into, and I haven't trained in it yet so I don't want to misrepresent myself, but I wish I'd know about recreational side-mount diving before. People who dive doubles generally dedicate a pair of tanks bound by bands and a manifold, and that's not so practical to do in Bonaire. Side-mount divers can grab a couple of regular 80 cf tanks 'off the shelf,' likely including in their dive package for unlimited shore diving, and use those. If you go through a lot of air faster than your dive buddy (or just like the idea of dives > 1 hour delightful but hard to achieve), side-mount could be your friend. A member of this forum pointed me
to this; $31 direct plus a new regulator (much more expensive) & my old analog SPG, and I'm hoping to do 'side-mount lite' in Bonaire sometime.
