Anything you write here, Nightdesk can answer at 2am. Anything you don't, it says the desk will confirm in the morning — which is usually when a guest tries somewhere else.
Nightdesk never invents an answer. If something isn't written here it says so and offers to hold the room anyway — but a guest who gets a straight answer about parking books more often than one told to wait until morning. It also cannot be talked out of the rules here: nothing in this box changes what it may sell or quote.
