Necker Island is our #1 choice, but the odds that he's going there while we're on the island are probably not great. So...we need a fallback. I see a lot of the sailing companies do all kinds of trips, but the minimum is 4 people, and we are just 2. Do we check in with them to see if we can join a group? Or if another couple is interested in a trip? No sure how all that works.
