I ended up leaving the bands that I used to play music with because I just couldn't stand the travelling, especially once we started getting occasional gigs outside the UK.
It's not that I lack curiosity about other people and places - they fascinate me, and I love learning about them - but I struggle too much with the transitions. Especially with a typical "vacation" of only a week or two, it's usually time to go home before I am anywhere near settled enough in the unfamiliar environment to be able to enjoy the experiences (or get any sleep!). And bus/railway stations and airports are second only to hospitals in my list of places that I least like to go - though I do rather enjoy the day-dreaming as the landscape goes part the window when I travel by train (if the carriage is not crowded, at least.)
The only holidays that I ever really enjoyed were solo hiking trips out in the wilderness, camping out in the middle of nowhere, as far from civilisation as I could get - sadly, I don't have the physical fitness to carry all that equipment these days.
Having said all that, I don't really feel like I'm missing out too much - for a couple of reasons.
For one, my "autobiographical" memory is absolutely useless. I think partly because alexithymia means that my memories don't really contain much in the way of emotional content. Once the holiday ends, it isn't long before the memory of it is little more than just a "fact" about the world, and I can't really remember the "experience" of it or how I felt emotionally. Past holidays don't seem so different to the fantasies I experience in dreams - and REM sleep is a lot cheaper than air fares!
The other reason I don't feel I'm missing out is because I am able to go on "holidays" that many other people cannot - every time I dive into one of my special interests, the total immersion is just like "being somewhere else". I can take a vacation in the "Costa del Music" or visit "Planet Computer Coding" whenever I have the time to spare, with no forward planning needed, and, so far as I can tell, with benefits for my well-being which are just as effective as taking a holiday for those folks who enjoy that kind of thing.
