Must say I'm much the same - a far cry from when I was young and almost permanently longing to get on a plane and go somewhere, anywhere!
However after many years of living abroad, plus dh and I have travelled extensively anyway, I don't long for it at all any more. When it's time to pack and go anywhere (unless it's maybe a short break in the UK - no bloody airports!) - I often find myself thinking I can't be bothered, I'd really rather stay at home.
I do usually enjoy it when I get there, but am always glad to get home - particularly to my own bed!
I'm much happier in self catering anywhere now - I often don't sleep well and really hate being cooped up in a hotel room with nowhere to escape to, to put the light on, read or listen to the radio, etc.
Dh still has itchy feet, always has had, but is happy to go on his own now and then, particularly to things I'm not really into, e.g. WW1 battlefields, and residential French courses in France. (My French was always a lot better than his anyway!)
