I never will understand why people who choose to go to a certain place on vacation, also choose not to follow the rules of that place, just because it suits them.
I have to be honest and say that I hope there are consequenses to this action. Maybe the housekeeper will turn the family in, or maybe another guest will. There is bound to be some screaming or crying from all those little ones, it is not like they are easy to hide! Either pay what you should for the room size that will honestly hold your family, or don't go. Be honest and pay what you should. Why is that so hard to do? Yes having a larger family is more expensive at Disney World, but what isn't more expensive for larger families? Would you go to a grocery store and take 2 dozen eggs but pay for only 1 because you didn't like the cost?
I also don't understand why people post about how they are going to do something wrong and then get all upset when people call them out for it.
