Hi Kelsey,
Welcome to planDisney, we are so glad you stopped by with your question about adding the Park Hopper Option to your Theme Park Tickets! My family and I love the Park Hopper Option, it really allows us to get the most out of our visits to Walt Disney World Resort, we love "Hopping" to a second Theme Park for the end of the day or even for dinner!
If you would like to add the Park Hopper Option to your existing
Theme Park Tickets the option will be added to every day of your Theme Park Tickets, not just one day. Because of this, I do recommend visiting Guest Services at the beginning of your visit to get the most out of the Park Hopper Option, you never know when you may want to jump over to another Theme Park. The additional cost isn't a per-day charge, it is based on the number of days on your Theme Park Ticket so the cost will be the same regardless of when you add the Park Hopper Option.
I hope you have a magical time at
Walt Disney World Resort, Kelsey. If you have any other questions as you continue to plan your visit please come back and visit us again at
planDisney. We are always happy to help!
