My favorite part of our DisneyWorld trip (besides not cooking or doing dishes for a week) was when Logan and McKay fought Darth Vader at Hollywood Studios. It was hilarious.
Logan took it all very seriously. Not a lot of smiles. He practiced and went up there and was very aggressive. We got to the park pretty early, but didn't get into a session until one o'clock. So we killed some time watching the Muppets, shooting at the Toy Story ride, watching a lame Pirates of the Caribbean show, and having some lunch. We were ready to go by the time we were done.
McKay made the audience laugh and cheer. He was the smallest one there, so they really got behind him. He got chosen to lead everyone out, and took his role very seriously. I wish you could have seen his face, he looked so scared and so so brave at the same time. He thought Vader was real, and that it is was his job to defeat him... no matter how scared. Hilarious. Afterwards they got to go to the Star Wars store where Aunt Julie bought them each a light saber that they got to customize and build themselves. They still haven't gotten old.
