Hi Anna,
You and your family are going to have such an amazing time during your upcoming vacation! With beautiful fall decorations, generally smaller crowds, the Epcot International Food & Wine Festival, and Mickey's Not-So-Scary Halloween Party, September is a wonderful time to visit!
I'm happy to let you know that to
upgrade your tickets, you'll simply pay the difference between the ticket that you have and the one to which you'd like to upgrade. With
current pricing, it will only be $25 (USD) per person to upgrade your 4-day Park Hopper Option tickets to the Park Hopper Plus Option. With that, you'll receive four visits to Disney's Blizzard Beach Water Park, Disney's Typhoon Lagoon Water Park, Winter Summerland Miniature Gold (prior to 4:00 p.m.), Fantasia Gardens Miniature Golf (prior to 4:00 p.m.), Disney's Oak Trail Golf Course, or the ESPN Wide World of Sports Complex. You'll be able to use these four fun visits however they work best during your trip, but just know that they're counted by visits, not days, so if you enjoy a water park and a round of miniature golf on the same day, that will count as two visits. Also, your upgrade will be valid for the entire length of your visit as it's not possible to upgrade your ticket for just one day. You
could buy a water park ticket that's valid for only one day on top of your Park Hopper Option ticket, but it's a much better value to simply upgrade the tickets that you already have. All you'll need to do to upgrade your ticket is visit a theme park ticket window, Guest Relations location, or the Lobby Concierge at your Disney Resort hotel and a Cast Member will be happy to help you.
Thanks so much for visiting us at the Disney Parks Moms Panel, Anna. I hope that you have a truly magical vacation!
Missy
