Greetings, Mark Louie, and welcome to planDisney! I love that you have a little magic left on your
Disneyland Resort Theme Park Ticket, and park hopping is so easy there. I don't blame you for wanting to enjoy
Disneyland Park and
Disney California Adventure Park in a day. Let's look at some options you'd have to make that change.
I spoke to a friendly Cast Member who said you could upgrade to a
Park Hopper Ticket, but the price would cover all three days of the pass, not just that final unused day. In other words, you must upgrade the entire ticket regardless of the days already used.
If you decide to go that route, you will stop by the Main Entrance Ticket Booth to make this upgrade, and remember that it will also depend on availability. If there are no Park Hopper reservations available that day, you won't be able to make the change. The Cast Member also suggested you call the
Tickets line before your trip so they can double-check your ticket type and give you more specific guidance, but any upgrades will probably need to be made in person at the Main Entrance.
I hope your visit next month is practically perfect, Mark Louie! Even visiting one park will be magical, but I'm sending pixie dust so you can visit both. Please
stop by planDisney anytime!
Magic awaits,
Elaine
