Hi Juvy! Welcome to the Disney Parks Moms Panel!
While you cannot downgrade your ticket and choose less days or less options, you can absolutely upgrade your ticket! Simply visit any ticket window, Guest Relations location or a Disney Resort hotel lobby concierge and let them know you would like to change your 3-day ticket to a
4-day ticket with Park Hopper Option. The Cast Member will be able to upgrade your ticket and you will just need to pay the difference in price between your original ticket and the new ticket with the additional day and option.
Keep in mind that in order to
upgrade your ticket it has to be within 14 days of the ticket's first use and there must be admission days left on the ticket. In other words, if you have already used all three days or the ticket has already expired, you will not be able to upgrade any longer.
Enjoy your
spring trip, Juvy! There is so much fun to be had during that time of year!
