Hi Catherine, welcome to planDisney! An autumnal adventure in the Most Magical Place on Earth sounds just wonderful. Before you know it, you'll be walking right down the middle of Main Street U.S.A.
Upgrading your ticket to include the Park hopper option is certainly doable before you travel. If you purchased from the European Walt Disney World Travel Company site, please
call to upgrade your ticket ahead of your trip. I hope you were able to benefit from the
free $50 Disney Gift Card with a Ticket purchase of 3 days or more.
If you have some flexibility to spend more time at Walt Disney World (is there ever enough time?), I highly recommend a cost comparison with the
Magic Ticket - it includes Park Hopper and
Memory Maker to capture all those magical moments. This ticket often works out the best overall value for Guests.
EPCOT International Food & Wine Festival will be in full swing by your arrival date. Sampling delicacies from around the globe throughout the stunning World Showcase is the ultimate way to while away an afternoon! Catherine, I wish you blue skies and sunshine for your trip. Should you need any further help, we're always here to answer questions, Louise.
