Will hotel staff cause trouble if they caught someone meeting an escort in one of their rooms? Is it forbidden? Can they legally kick you out? 

High end hotels definitely won't let you make brothel out of their premises. So try to stick to not so popular hotels who would be happy with any clients.

Where are you based mate, maybe someone can recommend you a place. 

Don't worry about that mate, most of them turn a blind eye to that. Of course, it implies noiseless sessions, don't expect porn movie shooting action there.
