I love bringing first time friends and family to DL. My favorite part is watching their expressions when they walk down main street.
One story: So both my wife and I are disney fanatics who live in Hawaii. My mom would always get irritated when both my wife and I and her sister rave about going to DL, talking about, new rides/events etc. We go about 2-3 times a year. Finally I convinced my mom to come up with us to Cali for the 60th of DL. Although hesitant, she decided to join. We went to DL straight from the airport, and it was such a treat to see my mom so happy as she's watching Paint the night and holding/hugging her sister. It was so awesome to see my mom get so excited. Now she can't wait to go back again.
2nd Story: I convinced a friend of mine to take a trip with us to DL. He always hesitated saying its for kids etc. He decided to go as I convinced him we were going to Lakers and an Angels game, not just DL. He had no expression as he walked in the park. At about 1hr in, he looked at me and said "now I know why you guys like to go to DL, this place is awesome". He's been coming back with us ever since, and love to hear his story of how it felt like to walk in DL for the first time.
