If you want a private boat tour in Bonaire, use https://www.saltytoursbonaire.com/. We had a group of 8 (it allows 10, but that might be tight) and it was a blast! We even asked if he would come to Curacao the next day to take us out again 🤣 We walked to the meeting spot, took maybe 10 minutes. We were able to bring alcohol on the boat and he had a big cooler and ice to keep it cool. He provided water bottles. We had a 4-hour tour for $390. He took us where we wanted to go based on his suggestions. We snorkeled in a couple different places and we also did some tubing. Great day! Would definitely do it again!
