I was there last September, but not for long enough to provide much info.
Stayed at the Radison, down by the river. There were two or three very expensive looking girls in the bar who most likley were working. I was more intrested in eyeballing the waitresses in the Japanese resturant (such is my oriental fetish).
Assuming you find a girl I would doubt you would have any problems getting her to your room at the Radison.
