Hi, Julie! You must be so excited... your trip is just around the corner!
I'm assuming you'll be in town for the Disney Princess Half Marathon Weekend. The
runDisney Health & Fitness Expo is THE place to go to get official runDisney event merchandise, and there are some great vendors and speakers, as well (I've been known to buy several Sparkle Skirts here)! It's also where you'll pick up your race bib, shirt, and gEAR bag. The one thing you won't be able to purchase here, however, are theme park tickets.
You can certainly purchase tickets in the Parks at any Guest Relations window, and Disney Gift Cards are an accepted form of payment. You might want to consider getting your tickets online, which will save time when you arrive at the Parks. First of all, if you have multiple gift cards, I'd recommend combining them on the
Disney Gift Card website to make your online purchase easier. Visit the
ticketing page on the Walt Disney World website, and scroll down past the credit card information until you see "Pay with Disney Gift Card," where you'll be asked to enter the number on the back of your Gift Card. Cast Members are always happy to assist you with your purchase over the phone if that's easier. Contact them at (407) 939-5277.
I'll also be down there this weekend, Julie, and I'm so excited that they've extended the
2019 Epcot International Festival of the Arts through race weekend this yEAR! Noshing at the food booths around World Showcase Lagoon sounds like a perfect way to recover after running 13.1 miles!
