This is a very simple job for an absurd situation. I'm staying in a hotel. When you check in you have to sign terms and conditions which say "no visitors in the rooms at anytime". I'd like to confirm how strictly this is enforced.
My suspicion is that since different people work in reception at different times that no one really knows who's supposed to be here anyway. Visitors are probably fine as long as you're quiet.
I suspect someone could just walk in. If they're not carrying luggage and head for the lift then they'll be assumed to belong here.
So I'm looking for someone to attempt that. Just come in, get in the lift, go up to a floor, walk around a bit and then leave (showing you could have just visited someone and no one would have stopped you anyway or even known who you were visiting). Then report the information back to me.
Obviously, if you do get stopped don't tell them who I am or why you were here (you won't have my room number anyway).
Doors are locked at six PM (you need a guest key to get in) so this would need to be done earlier than that.
