Magic Kingdom not so magical

Barbs and I spent a week in Orlando on vacation earlier this month and four days at Disney World parks. Disney had a great vision but I'm not sure the parks bring about what Disney intended. He called the place the happiest place on earth. At 3 PM on the first day at the Magic Kingdom I didn't see many smiles. As a matter of fact, most of the people seem tired and angry. Why was that? At the happiest place on earth of all places.
