My last few stays in hotels, at the desk they have given me two key cards, but I only need one.
So problem here how do you get the other key card to the escort, possibly a hard thing to do
Best thing is let her know you will meet her in the lounge, have a talk, and maybe a drink. Give her the key card, and let her go to the room and get ready. And you then follow up, in around 10 min's, and all your valuables are locked in the safe, so no worry things going missing
