Welcome to the board.
Personally, I don't bother with boat dives on Bonaire, I much prefer to do my own schedule. Once in a while we will do one or 2 to Klien Bonaire (a small island about 1 mile off the main island) but we never buy the package. There are some nice dives on Klien Bonaire that are worth doing but with a few exceptions, the "mainland" dives the boats do, you can shore dive the same spots. I often use the boat mooring blocks as my entry/exit marker. Don't assume the boat dives are better than the shore dives, they are not. If anything, the shore dives are better IMO. Most ops want you back at the boat in an hour, my average shore dive is 75 minutes and some go as long as 90. At Buddy, all you have to do to add a dive is to sign up for it on their dive boards and it's added to you bill so adding one or 2 is very simple. You run a tab with the dive shop anyway so it's no big deal. The per dive cost for the 6 dive package is a little less but not by much. The single dive is in the $25 range. A word of caution (?), a lot of times the boats at Buddy fill up quick so if you want to do boat dive, reguardless of wheather you have a package or not, you need to sign up early. Most people who have packages will sign up for the next dive as soon as the boat returns to the dock. It is possible to have a package and have difficulty getting on a boat. Another reason we choose not to bother with boat dives.
Buddy is a greaty operation. Super staff both at the dive shop and the resort, you will enjoy your stay.
