Yes, my last dive trip will be July 2016 to the Red Sea, where I have booked back to back liveaboard trips to the far north and central destinations.
The retirement was planned and not enforced. I do enjoy my diving a lot but I made a promise to my wife 9 years ago when I started diving. We put a lot of land based holidays on hold to satisfy my diving bug and it was agreed that I would dive for 10 years and retire. Afterwards, we plan to start going to all those other holdays - Inca Trail etc in Peru, Central Asian Silk Routes, Patagonia, Madagascar (not to dive), Transylvania, New Zealand etc
Sounds like a good plan to me.
We have a similar plan. My bride likes the camping/hiking thing, and I believe the Hampton Inn is roughing it. So she's going to do the trips i wouldn't enjoy (she just got back from a rafting trip down the Grand Canyon) and I'll punch a few of my dive bucket-list items over the next few years. Then we can do some civilized trips together. For example, I want to rent one of those canal boats in the UK and do a pub-crawl on the canals.
