Hi Joseph! Welcome to planDisney!
You're headed to
Walt Disney World Resort during a spooktacular time of year! Not only will you have the chance to check out
Magic Kingdom decked out in all of its seasonal fall decorations but you'll also be able to visit EPCOT during the
EPCOT International Food & Wine Festival! Some people head down to the Resort specifically for one event or the other but I think you'll certainly have the best vacation ever if you choose to see (and try treats at) both!
Joseph, you are certainly welcome to upgrade from a
Standard Theme Park Ticket to one with the
Park Hopper Option added on. In fact, you might even be able to make this upgrade right from home on your
My Disney Experience mobile app. Simply tap the three horizontal lines in the bottom right corner of the open application and then click "Tickets and Passes". From here, choose the Ticket you would like to upgrade and click "Change Ticket" before completing your purchase. You're correct that the difference between a one-day Standard Theme Park Ticket and one with the Park Hopper Option added on is currently $65.00, though prices are always subject to change.
If you'd rather wait to upgrade until you're at The Most Magical Place on Earth you're welcome to stop by any Guest Relations desk at any Theme Park or the Disney Ticket Center at
Disney Springs before you swipe in for your day in the Parks. Don't forget to make your Theme Park Reservation for your first Park of the day!
I hope you take advantage of the flexibility that hopping from Park to Park gives you! I love being able to begin my day at one Theme Park and then glide high in the sky on the Disney Monorail or
Disney Skyliner to another for the evening. You'll get to see so much more of the "World" this way!
Have a magical stay at Walt Disney World Resort!
