Plaza Resort Bonaire (http://www.plazaresortbonaire.com/) is a good place to stay, though I've heard there are some places that cost a bit less but maybe not as nice.  This place has it all, though, especially if you are a SCUBA diver.  Bonaire, in general, is one of the best places I have ever dived.  It is very easy beach diving.  Just rent a pickup at the airport, get your gear and go around the island to the marked sites (look for a painted yellow rock or two w/the dive site name on it) and park on/near the beach and go.  It's really easy. The nightlife is so-so.  I found the service to be really slow.  Maybe it depends on where you go, but of the places I went to (can't quite remember the names right now), they were generally slow so don't expect fast service. Bring snorkeling/SCUBA gear, camera, sunscreen, etc.  The visibility underwater is probably 50-80 feet, perhaps more.  The whole island is a protected marine sanctuary. Getting around: you can rent 4 door pickups at the airport and beat-up motorcycles in town.  If you stay on the main roads you'll be fine, but if you venture off, you could be in trouble as sometimes the road really dissolves into remnants of what might have been a road years ago.
