It's hard finding those 5 star hotels that DONT have keyed elevators.  
So for discretion, I can only stay at places like The Trump, Chatwal if I am seeing one person that day.
But when I do find those without keyed elevators I put them into my rotation of hotels to choose from....
Any providers with 5 Star hotels that aren't keyed access only please send them my way!

but it seems the agency found a way around it, I just went on the elevator with a bunch of touristas and told one of them to press 22 for me and they did. So polite these tourists!
