I don't know why Bonaire has this reputation you all think it has. I don't think it's boring at night there at all!
There are casino's in the Plaza Resort and Divi. Even if you don't gamble, it still keeps people 'up and about' through the night.
There are tons of very good restaurants to choose from.
One of my favorites is an Italian place. The owners came to Bonaire from Italy, fell in love with it, and stayed. It has the best Lasagna I have ever had. It's called Capriccio's. ( Herman I'm sure now)
Richards, another popular place to eat, is very romantic, and you can watch the sunset while dinning.
The downtown area has a pier with a bar at the end of it, that is a hang out for tourists and local dive guys.
We have met the manager of the dive shop there with his local friends and had some beers with him.
Really Bonaire is just that kinda place. Easy to mix with the locals, and get the feel of the island.
Not sure what kinda action everyone is looking for. Cancun?
