Hey there, Lynn! We appreciate you bringing your ticket question to planDisney and I would be happy to help.
Currently, all ticket upgrades are done at the Main Entrance Ticket Booths and I get your worry about having to wait until you arrive to upgrade your ticket. It is very possible that the days you need could then be booked full for reservations. If you have questions about upgrading your ticket, I suggest reaching out to
Ticket Services.
I do want to let you know though that you cannot upgrade a ticket to add Park Hopper or
Disney Genie+ for only a few days. Park Hopper and Disney Genie+ ticket add-ons can only be added for the complete length of the ticket. The Park Hopper option is one flat fee per ticket, so it doesn't matter if you are upgrading a one-day ticket or a multi-day ticket, the price is the same. If you only want Disney Genie+ for a couple of days of your ticket, you can add this to your ticket any day as soon as you enter the park for the day each day that you want to use the service.
Lynn, I hope this is helpful as you go to upgrade your tickets. Please come back and see us again if you have any other questions as you plan your visit.
Carrie
