If I think I just can't work without multiple monitors and a high-end office chair (and maybe printer), I probably won't travel or I'll get a co-working space of some sort. When I traveled a lot for work, it was some combination of the event/trip was my working and/or I just worked on my laptop wherever.

I'm semi-retired now but I'm temporarily staying in a Marriott property (Springhill Suites) that does have a usable desk and office chair which is just fine for writing at for me--though people with very specific requirements probably wouldn't like it.
