(I used to do a lot of work photographing escorts.) A little of both, depending on the "class" involved, and the location. You might be surprised to learn that a lot of prostitution happens during the day-time. In largish-hotels a bloke going up to a room, spending 30-60 minutes there, and coming down wouldn't stand out. Even if the same host entertained 5+ people in her day. (Unless you get involved in high-end work you'll virtually never have an overnight booking. Average duration amongst the people I knew was 60-90 minutes.)
