Not had it myself yet, but I'm noticeing more and more pro$$ies working from hotels these days.
Probably due to a number of contributing factors, expensive rents, heat from police, neighbours, etc......
Can only be a matter of time before more hotels clamp down, imo.
My guess is that it's the rents too. It makes more economic sense for a girl to book a room a month or so in advance to obtain the cheapest rate. To pay rent for a whole place is going to cost a lot more than it is to 'squeeze' your hotel bookings into a few days. Add onto that those who tour and it makes financial sense. There's also the bonus that you don't have to tidy the place up!
And trust me, I've visited a couple of houses where I've wiped my feet going out! But perhaps that's just the quality girls I choose!?
Mind you, I think in the long term, hotels are only going to work for the better looking girls who have more to offer, judging by who does it in my area.
