Hallo,
I have been to Bonaire a view weeks ago. And it was great!! I loved it. I did a lot of thinks like diving and I also had rent a car at rento fun. Now I see a lot of people who likes to know were they can rent one. So I might help you with telling you that. You have to be in the main street of Kralendijk. They have al kinds of things and the service is fine.
