Hi Maribel! Thank you for bringing your question to the Disney Parks Moms Panel.
You are welcome to add the Park Hopper Option to a previously purchased ticket. All
ticket upgrades must be done in person before the last valid day of admission on your ticket expires, and within 14 days of first use.
It is not possible to purchase the Park Hopper Option for only some days of a multi-day ticket. You may add the Park Hopper Option whenever you wish (prior to the ticket expiration), but it will be the same cost whether you add the option on the first day or after you have used 3 days; the Park Hopper Option is applied to the entire ticket.
If you think you would like to visit multiple theme parks on the same day at least some of the days during your visit, I would go ahead and
purchase your Ticket with Park Hopper Option now so you can use the benefit for all 5 days of your ticket. The Park Hopper Option is a great way to take advantage of
Extra Magic Hours and
extra, Extra Magic Hours if you will be a Disney Resort Hotel guest. We sometimes like to Park Hop to view a
nighttime spectacular at a different theme park than the park we visited earlier in the day, or perhaps revisit one of our favorite
attractions.
Maribel, I hope my explanation about purchasing the Park Hopper Option is clear. If you have additional questions, please feel free to visit us again.
Have a wonderful visit!
Anne Marie
