Manners have gone out the window. And the parents are at fault. I swear, there were kids totally out of control on our last visit to WDW, and the parents never reprimand the kids at all. They can just do whatever they please, and at any hour they please. It's absolutely ridiculous.
And what's worse is when you call management, and they don't do anything about it either.
I NEVER let my child behave like that in a hotel corridor or in common areas. It's just inconsiderate of others, and kids need to learn that they are not the center of the universe 24/7.
