I don't think so. I identified with some of it, and I'm rarely homesick. Confined and dissociated, though: in hotels, I feel like that regularly.

If I am travelling by myself and staying in "international business bland" style hotels I can definitely suffer from those feelings - I've certainly woken up and wondered which city/country/continent I am on!

Same here. I've travelled quite a bit, and I don't generally feel homesick, specifically. "Dissociated" is a word I use often. If anything, I'm 'homesick' for multiple homes: I am constantly missing Athens, Kiev, Tokyo, Berlin...

In many ways, constant travel is really wonderful: I'm almost always saying 'hello' to new friends, and 'hello again' to old ones. At the same time, though, you're constantly saying goodbye, as well...
