Staying at the Bellagio for the first time and just wondering how tight security was in regards to bringing in a provider. Any tips or recommendations,failures...etc. Thanks

Need to show a room key to get to the elevators, (24-7)
Not a problem though. I normally meet  my  date at the bar area or at the bank of pay phone around the corner from the elevators and take them up. Have seen girls waiting in the area just in front of security for the guys to come down and escort them up.
Have fun.

Isn't that why they located the gift shop there so close to the elevators, lol?  That way they don't look conspicuous or feel uncomfortable while waiting, they can just look like they are shopping.  Then you can come down and meet them, maybe buy a few snacks, etc, and go back up just like all the other groups of guests.  Trust those Bellagio architects to think of everything!!!

The gift shop is a great place to browse for all sorts of lovely treasures -- ALL for sale.
