There have been some great suggestions in this thread, I'll just add a few from our experience. We started taking our girls in 2016 when they were 9 and 12, and it has been beautiful to watch their growth over the years in terms of how they can handle the boat, dinghy, etc. - so I hope you keep taking them!
With this said, my wife cried twice on the first trip (never good, right guys) because we failed to help the kids understand how they should help - so the adults can also enjoy the trip. We were doing too much for them so they would enjoy the experience, but we were putting too much on ourselves. Overall, we have learned that the responsibilities on the boat need to be a team effort (cooking, cleaning up after meals, cleaning the boat, getting lines and fenders ready, etc.).
I learned on our first few trips not to push too hard in the early days of the trip. Of course, your kids may be different, but one of mine needs a few days to get her sea legs. Therefore, we try to have extended mooring/anchoring time in a beautiful spot on the first few days. As mentioned, a highlight for the kids is jumping off the boat - take a skip ball, football, or something like this for them to throw and catch while jumping off to add some fun.
Our girls also aren't huge Anegada fans, but as they have aged, they appreciate the food at Wonky so much that they want to go. We like it, and since our trips are also for longer than a week, we go. With 10 days, you have the time, but taking the tour (mentioned above) may help the kids experience. We haven't done this, so I can't provide feedback.
Our girls do jump off Willy T, and they love it. Although, they have seen nudity in the afternoon a few times. We have used it as a teaching moment. We also enjoy finding good spots to jump off the rocks around the Baths. I use the dinghy to get them in position, but you obviously have to be careful.
Snorkeling is a primary activity, but I have learned to put them in calmer spots since one of my girls panics some if the water is rougher. It doesn't bother me, so I had to learn to consider the fear the kids may have.
Last, we get a ski rope and pull the kids behind the dinghy on the paddleboard. The type of paddleboard will impact their maneuverability in and out of the wake, but the team at BVI SUP CO has been great over the years helping me pick a board that fits all needs. This year, my daughter brought a ring float and sat in the ring on the board while dinghy skiing. It was a new twist and they had a blast.
Overall, the years of memories are so worth the few challenging times you have while learning to do the boat with kids. It has become a special family vacation for us, and I hope you experience the same! Best of luck!
