Hi Emily,
From the moment you enter the Walt Disney World Resort welcome gates, you'll find that Disney Imagineers have thought through every little detail about your vacation experience and Cast Members are there to do all they can to make your visit completely magical! That's the Disney difference!
I'm happy to let you know that you'll find courtesy trams at all four theme parks that will transport you from the
parking lot to the entrance of the theme park. Be sure to follow the Cast Members' instructions about where to walk and how to board to make sure that you and anyone traveling with you stays safe, and if you have a stroller with you, you'll need to fold that up to board the tram. Within just a few moments, though, you'll be at the theme park, ready for a day of magic and fun! The trams run throughout the day and even for awhile after the theme parks close, so after you've enjoyed everything the theme park has to offer and you're ready to head out, you'll find a courtesy tram to take you back to your vehicle.
One tip I have: Take a photo of the section and row where you're parked in the morning. You'd be surprised how hard it can be to remember that information after you've experienced so many other incredible things in your day! Tired Mouseketeers (of ANY age!) wandering around a parking lot looking for a vehicle isn't quite the magical end to your day that you'd like to experience! However, do know that if something like that were to happen, there are Cast Members available to offer assistance! (Remember? They really do think of EVERYTHING!)
Thanks so much for visiting us at the Disney Parks Moms Panel, Emily, and please let us know if you have any other questions as you're planning your trip! I hope that you have a truly magical vacation!
Missy
