When Ji stayed downtown where you needed a key to use the elevator, she would ride down the elevator, and stay in it for you to see her, make eye contact, and you would go into the elevator and follow her. If others were in the elevator she would pretend not to know you, but you would see the mischief in her eye. Once in the hallway alone with her, she would skip and laugh about being mysterious, even pinch your butt. Everything she did was a turn on!!!
Once she knew you she would tell you the room number and see if you could just jump into an elevator someone else has used their key to go up, but she would come down to get you if you called to say nobody was going up. At least in Wpg there are not security people watching everyone, not like Vancouver where many hotels try to stop SPs coming to see you.
