Plus people that do like to spend much of the year travelling around doing deep work are (i) relatively likely to book short stay apartments instead of hotels and (ii) relatively unlikely to be particularly fussy about working environments since they're actively choosing travel over convenience and optimal working environments

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.
