Bonaire is not exactly known for all-inclusives; the main one I hear mentioned is
The Plaza Beach Resort. Haven't stayed there. A Scuba Board 'invasion' event of Bonaire was held there in 2013;
a thread on that. They do list massages as an extra charge option; not sure what all you're after with a 'spa.'
The upscale resort in Bonaire, from what I've read (since I haven't stayed at it, and don't recall any trip reports here off-hand from those who have; perhaps a Search world turn up something?) is
Harbor Village Beach Resort. Of course, I suspect on some level you get what you pay for, and you do pay...
Of course, any resort with an on-site restaurant you like becomes a de facto 'A.I.' for food if you just eat there every night (or however often) and pay as you go.
Finding a way to get
at least 3 boat dives/day could be a challenge on Bonaire; it's heavily conducive to shore diving. When I stayed at Buddy Dive Resort a week last year, I only saw one 2-tank trip (as opposed to 1-tank trips) that week! Other resorts may do things differently, but I'll be very interested to see if you find somebody who's reliably going to get you
at least 3 boat dives/day there.
I love Bonaire, but I wonder if it's what you're looking for. Where else have you dove so far, and how'd you decide on Bonaire?
