I am going to talk to the manager when we arrive about security issues. They will clearly understand that if anything is stolen from the rooms we will NEVER return to the island. Also, I will boycott the island to all on this website and anywhere I see divers. Yes, the resort should provide good security for our rooms since I am a guest.
Do what you want, but it's possible they will find that approach insulting. I know I would, especially from a newcomer. They're open, friendly, welcoming people at BelMar. Once you're there you'll realize that it's completely unnecessary to threaten them.
BelMar has excellent security. His name is
Butchie. He knows all that happens there. You'll meet him the 1st night you're there. If you arrive after 5pm he'll be the one waiting to show you your condos. And explain the A/C etc. And he'll likely be nearby anytime you park at night both helping you park (it's tight) and checking to make sure you belong there. It's a width compressed property, so very easy for him - or anyone- to watch for any unusual activity. Belmar is in a quiet neighborhood so it's noticeable even when someone drives by or walks down the street at night. Mostly you just hear the donkeys...
Daytime the office ladies can see the entrance to all the units on the streetside. And no one is coming in oceanside unless they're swimming...
We left our doors open most nights (there was a fieldmouse that used our unit more than once to keep from having to run the south bushes Iguana gauntlet) with no problems. We usually locked the doors when we left although I think we left the patio doors unlocked once or twice. I don't think the people next door ever even closed theirs all week - no A/C except in the bedrooms so the cross-breeze is nice.
Not that I don't sympathize with the OP as I think what happened to them is terrible, but I'd be more concerned about my stuff being stolen flying through San Juan than I would on Bonaire.
But I also wouldn't let the hysteria generated in this thread - a lot of it by people who've never even been there - ruin my vacation.
Even the OP who had all the grief seems more interested in resolving the problem by bringing it to people's attention than boycotting Bonaire - at least that's my interpretation.
But that's just me...
