Diving in Palau and Yap — some of the best diving on the planet, and about as far from home as you can get. I have never gone. It is expensive, it is a long way to travel, and right now it does not interest anyone else in our family. So it stays on the list while the kids are still young enough to want different holidays. Nothing dramatic about the wait, just sequencing. My turn is coming; theirs is now.
