From a 'dive experience' standpoint the current impact of SCTLD is negligible. Yes, it's there if you're looking for it - and there are some obviously dead patches - but there is just so much other healthy 'stuff' that there is no reason whatsoever to consider avoiding Bonaire as a destination. From some of the earlier posts in these threads it's possible to assume the reefs have been turned into some barren wasteland.
Was there for a week two weeks ago, first time. I did find the constant disinfection and rinsing multiple times a day such a PITA that . . . .
In my decision to nudge our regular (not quite annual) Bonaire group trip elsewhere this year (we went to Roatan), my thinking (posted upthread, I believe) was not that the effects of SCTLD on Bonaire's coral are worse than on other Caribbean dive destinations but rather that trying to comply with the requirements for choosing dive sites according to a color code scheme and disinfecting at certain points in this routine would be too much for our group to handle. We normally have enough difficulty over breakfast just deciding on what sites to dive and getting ourselves out the door (the proverbial herding of cats). Depending on how you like to do your dive trip, Bonaire can require just a tiny bit of logistical thought. Before the SCTLD mitigation measures, my group was already on the edge of being unable to manage the logistics. I have no faith we could adhere to the current rules and still get the same amount of diving in.
Mike Walker's comment suggests to me it's possible that Bonaire's mitigation measures are working, or that groups like mine that might bungle the rules have stayed away.
