Besides being against the rules and totally too many people to fit comfortablly, you need to think of some other consequences of this plan. If you try to "sneak" an extra person in who is not on the reservation, you will be very unhappy when you try to do some of the extra benefits that come with on-site accommodations. For example, only those with room keys displaying their names will be allowed to take part in the morning and evening extra magic hours. And YES, each of the children will also have their name on a key since those "perks" are tied to that "key to the world". I'm just pointing out that trying to cheat the system will ultimately cheat yourself as well. Besides, I don't want to pay the extra maintenance over crowding a room might lead to.
