You picked the right place to bring the RB - Walt at Rec Tek on-site there is the go to guy for needed supplies.
Rec Tek Scuba Bonaire - We do it silent. We do it deep. Techincal diving.
Pictures of a lot of the entries - most require some scrambling over ironshore so bring treaded boots:
Scuba Shore Diving Region: ABC Islands
Bonaire is all small stuff, the biggest things typically seen are rays and tarpon. Seahorses are pretty common, nudibranchs, frogfish etc.
There's sort of a double reef starting south of the airport that runs to almost the tip of the island. Typically there's more current at the farthest south sites near Lighthouse and the north sites in the Park. If you want to dive the park sites, Buddy Dive next door runs a 3-tank boat dive - the drive into the park to those sites is for the adventurous - those equipped with spare tires. (lots of thorns)
Cliff - the dive site north from Habitat's dock - is among few vertical walls on Bonaire. Nice dive. Another good dive with the RB might be to go spot fish at Bari Reef - most counted species in the Caribbean. My buddy did their REEF count - one dive they (he and DM) spotted 185 different species on OC. You should probably have time to find 300+ lol...
If you're doing deep dives the Windjammer is the signature Bonaire wreck. 175' plus. Walt dives it. Hilma Hooker is the signature wreck for the rest of us. Other good dives - Angel City, Invisibles, 1000 Steps, Karpata (rougher entry) Bari, Vista Blue in the morning. Salt Pier is not to be missed also if there's no ship loading. Rappel is one of the better boat dives and do a couple dives to Klein Bonaire also - we liked Forest a lot.
Weather wise it should be hot and dry - it was over the 4th of July when we were there. The ABC's are below the hurricane belt so not as affected. With the Mangroves and the Salt Pans there's lots of bugs though - not so much at the ocean-front resorts.
In town, one not to miss is It Rains Fishes for a nice upscale meal.

We also liked Donna/Giorgio's but haven't been there since they moved.

I've heard good things about Capriccio also but haven't eaten there.

We had a decent meal at RumRunners one night also. Nice view from the patio. I assume your package includes some meals there.
