Many times and never had an issue or a problem with them.  You just have to go down and meet somewhere.  There is a "piano bar" right by the front that's an easy place to meet or just about anywhere else for that matter.  There is a little store right across from the elevators that's an easy place to meet too.  It's a great place to stay.  I'm sure you will enjoy it.

best thing to do would be to meet your date and slide her a key and a hug and walk up seperatly .
Then your still beeing private especially if your planning to see multiple providers.
See you at Sema

Never had a major problem at Bellagio but almost with my review of Tiffany.  She was dressed like a call girl in a rap video and when I met her at the bar I was very nervous.  (See my review of Tiffany)  When we went to the elevator bank I just knew we were going to be stopped..  I got the nastiest looks in the world by the hotel security but they let us up.  I did however receive some more nasty looks when I came downstairs by myself an hour later. I have had a few ladies at the Bellagio and that never happened but this was very very obvious and I think that is what alerted the security guys and what ticked them off.  because of this I stayed at a hotel with no security on my last vegas trip-see Tasha's list for hotels without security at the elevators.
