Check a hotel booking
A hotel's booking form sends a dictionary. Before confirming, check it and return the list of problems, in this order: the room type isn't one the hotel has; the number of nights isn't 1 to 14; the number of guests isn't at least 1 or is more than the room holds. An empty list means the booking is fine.
