Paul's isn't the greatest but all the rooms have exterior access, no elevators, just exterior stairs.
I think the zen hotel is set up the same.
I guess the big thing would be does she want to dress up slutty, & if so how comfortable does she feel strutting her stuff.
There are quite a few nice hotels, some with key access to elevators, etc. maybe she'll get a thrill out of walking through lobby with or without you. Maybe she wants to walk up to hotel clerk & ask for room number or if you could be called.
All kinds of ideas.
Personally I've had a really good friend who wanted to do a similar scenario, she was dressed to the nines, not too slutty so she didn't stand out too much. She wanted to be a street walker. To make a long story short, I picked her up on a corner after dropping her off a few blocks away & watching her as she walked along. She even had a few vehicles stop before I drove up. It sure got her horny
I guess that's why I started seeing sp's.
Good luck
