I worked one summer at a five-star hotel in a ski town in the rockies. At various times and for various clients (typically on short notice) we (1) hosted a banquet for a former U.S. president that involved locking down the hotel with the secret service, (2) drove 2 of the hotel's SUVs 100+ miles round trip to buy dozens upon dozens of suitcases for a member of the Saudi royal family, (3) turned a conference room into a fiber connected operations center for a team of high-frequency traders that was visiting from NYC for two weeks.
I am certain that the hotel manager would have told all of these guests that we would absolutely find a way to handle their requests, no problem. And we did. That is part of the reason they were at that particular hotel in the first place.
If the hotel you are talking to is ready to make crazy things at crazy prices, they will answer “yes” to anything that can be solved by throwing money at the problem.
On the other hand, for hotels that don’t deal with lunatics, they will refuse to deal with you the moment they smell your problem is bullshit or unreasonable.
In the end, I’d think false positives would be extremely frequent with that approach.
