Hello to my fellow Philly native! I'm from Levittown...
Anyway, how are you getting to the "World"? Are you flying or driving? Will you have been driving the whole day? Depending on your answers to these questions folks can better give you an idea of things to do on night 1.
Normally, we have had a long drive (we stop overnight in Lumberton, NC) and can usually get in to Disney by about 3:00pm or so. From there, we check into our resort and then head out to a dinner reservation. We have enjoyed our first night dinner at Chef Mickeys many times. Plan dinner for around the time Wishes will be shown at Magic Kingdom and take a walk out on the observation deck and check the fireworks.
Have fun!!!!
