I have done that lots of times in my 7 yrs of hobbying. My rule of thumb is never ever take a SP overnight if you haven't met her before. If there is no chemistry, you are wasting your money and time. Most of my girls were Asians with not much knowledge of the city plus they are cute small spinners so not much of a physical danger to worry about. Just keep your valuable out of sight. Just ask her what kind of breakfast she likes before she went to bed. They tend to sleep in late. If she is Korean, just give her a bottle of Soju and she won't think of anything else than get drunk a little get fuck and have a good night sleep. Most of them are here under visitor visa and quite lonely at nights and they appreciate your companionship overnight. Some of them i booked for over night thru agencies, some just dating after their shifts. So far no drama yet.
