We did exactly this with our kids (15, 13, 13) in 2016. Could not have gone better. We did a DSD in the pool locally, just to make sure they still wanted to do it, and did not have any issues with it. They did E-learning followed by pool and dives in Bonaire. Gave the wife and me a few days to get reaquainted with the island and do a couple deeper dives including the Hooker while they did class.
