When we got married we lived in Northern California, which is a 6 hour+ drive (depending on traffic) to DLR. The bulk of our guests drove down caravan style, with many family members carpooling together. Our bridal party and some of the guests flew down. At the airport we rented a limo to take the group of us who flew together to our hotel. This option was more affordable than using Super Shuttle and nicer than a taxi.
As for incorporating a Peter Pan theme, here are a few ideas off the top of my head:
Sprinkle pixie dust on the tables (sparkly confetti)
Name the tables after locations or characters in the movie (Neverland, Indian Village, Lost Boys Cave, Skull Rock, Captain Hooks Pirate Ship, London, Mermaid Lagoon)
Use lanterns as table displays, I recall there beinga few in the movie
Treasure chests as favors, pirate loot ala Captain Hook
Play "Followingt he Leader" as the bridal party make their entrance at the reception.
If tiger lilies are real flowers you could use those.
Take a picture using a teddy bear and umbrella like John and Micahel.
Place a clock like Big Ben on your invites
Do you ahve a reception site selected yet?
