Very glad you made it and now have a shared experience with many of us. A few observations from my 8 trips (the last solo):
1.) As others noted, group dives close. I like to do 2 in the morning, come back for lunch, head out & do 2 in the afternoon, and maybe a night dive on the house reef. If I felt the need to make the night dive a new site off somewhere, that would be a hassle. To pull this off, my last trip I ate supper at Buddy Dive every night, and breakfast buffet was included; lunch was in room simple stuff from the grocery store. I'm no athlete & it was tiring, but fun.
2.) Food's pricey. I bought 20-packs of Coke Zero at Zhung Kong supermarket, PB&J sandwich fixings & canned fruit cocktail, that sort of thing for lunch. Breakfast buffet included at Buddy Dive Resort. Ate at the resort restaurant in the evening. After traveling around to eat my 1st 7 times, the 8th, I stayed 'home' and kept it simple. A tank of gas in the truck at the end of the week can set you back $80.
3.) That 'you're on your own' thing is a big selling point to shore diving despite the harder work compared to boat diving. Offers the chance to foster some independence. I like both methods.
The crime thing merits its own section, for those who've not been & may use this thread to research. As any populated Caribbean isle will, Bonaire has crime. But it's considered by some one of the safer places, especially in terms of violent crime against persons (which it seems there have been more reports of in recent years, judging from online discussions, but I still felt safe out & about day or night).
Bonaire is famous for petty theft out of parked dive trucks. Divers gear up, go in & locals (on this rather poor island) know the rich tourists are gone for about an hour. So a few criminal types search the trucks for stuff to take. The 'house rules' are leave the doors unlocked & windows down so they don't break in, take the key with you and don't leave anything valuable in the truck. Odds are good you'll lose nothing. I've left cheap sunglasses & plastic bottles refilled with water without incident. Cheap sandals or a raggedly looking old t-shirt might be okay.
But don't leave a cooler with food/drinks, a camera, change of clothes, etc... If it would bother you to 'donate' it, don't leave it in the truck while you dive!!!
This is how the place operates. With the (seemingly rare) exception of battery theft or occasional gas siphoning, you can practically eliminate yourself as a truck crime target. This is common knowledge.
Some people will not accept that. In this case, 2 out of 4 trucks got robbed. I'm guessing you know 2 because something was taken from each? Which implies something was left?

P.S.: Please list the dive sites you hit. In your other thread you asked our favorites; I'd like to hear what all you chose.
