As with most things I'm with Dickhead
Why pay them to sleep? I'm a late, late night person myself usually making my selection around 3ish in the am. After we are done most of the chicas I'm with are heading home. I tell them they may stay if they wish, some do some don't. Only one asked me how much, and I told her she could stay for half the price of my room for a day, she didn't appreciate my wit needless to say.
My Carolina from Cattos fell asleep after having her carpet furiously munched. I thought "what the hell" and drifted off as well. When we woke up she was in a panic seemed she had overstayed her babysitter and wanted me to pay her and leave. I told her of course I loved her but only one of us had sex before she dropped off to sleep and I wasn't paying her for eating her pussy and knocking her out. At first she was pissed but after I held my ground she fucked me very, very well. Proved the point that they honestly respect you more if you display your cojones in your dealings. One of my buddies once pulled a favorite from Cattos at 0200 and stopped off and got a bunch of blow, weed and a bottle of champane. She was still there when I called him around 10 for breakfast.
My 02 centavos would be this. If your pulling them out of the club at 2300 and want them to spend the night it's gonna cost you extra as it should but if the session is over at 0500 tell them they can stay if they want. If you do make sure your camera, passport, plane tickets, money, etc. are in your safe. If you don't have a safe with a good combination lock then you shouldn't be asleep while they are there. Richard T is the exception to this advice because He's not pulling any chicas that he hasn't done many times before. If they steal his laptop He knows where to find them.
