So you solved your own problem. Great job. Having the girl surrender ID is a little bit of a hassle but its for your own good. All the girls you meet will know if a certain hotel is "friendly" or not. The 2 guests at a time is probably not enforced but intact in case you are making too much noise. I have never had to pay anything extra for a guest or guests, but again, the girls will no the ropes of all hotels. Relax and go to it.
