I will be visiting Later this month for work and will be staying at Mandalay Bay... Looking for suggestions in discreet ways to connect at that hotel as I know a key card is required for the elevators.

I stayed at MB a couple of months ago. I met the girl right outside the elevators right by the cafe thats next to the elevator bank.  

There’s a lounge right off the elevator lobby called Hazel Coffee and Cocktails; very convenient to meet there and make your way up to your room.  

i have had a person meet me near or inside the store by the elevator and just slip me a key, or wave and then i following them up just a few feet behind

I like this as I’m not as concerned about security as I am my clients

I always self park so I typically will meet my client by the Parking garage to get a key or I will follow behind them and walk past elevator security they get the hint when its a beautiful woman .

I’ll have to figure out parking ramp,  I like that idea.
