International Hotel Law

[snopes]

Comment: Could you please post something about the "International Hotel
Law" that supposedly states that a hotel cannot ask a guest to leave even
after the agreed upon check-out time, if the guest requests an extension
and has the ability to pay for it? I keep getting guests try to use this
all the time, but the truth is that we can forcibly remove them if
necessary to make room for new guests, since we are not bound by any
"international" laws here in the states, and the laws we are bound to say
that we must have rooms available for those who booked them - meaning that
if I'm sold-out for a night you want to extend, I can ask you to leave, so
that I'm not liable for booting a guest who had a valid reservation.
