Hello there, Teresa!
Welcome to the Disney Parks Moms Panel. You are in for a spooktacular vacation full of happy haunts and ghoulish delights at the Disneyland Resort for
Halloween Time. I love that this holiday can be experienced around every nook and cranny of Disneyland Park and Disney California Adventure Park. With Halloween-themed attractions, decor, treats, and even Characters in costume, you are going to love this time of year.
Since you have tickets to Mickey's Halloween Party you get to have even more fun with exclusive Character meetings, fireworks, a parade, and of course trick-or-treating. Don't forget to dress up for the party as this is one of the only events where adults can come to the park in costume!
You are more than welcome to
apply the value of a standard park ticket to a Disneyland Resort Annual Passport purchase, but unfortunately you cannot upgrade your Mickey's Halloween Party Ticket to an Annual Passport. That was a great question, though! If you plan on upgrading your regular park ticket to an
Annual Passport, you can do so at any of the Main Entrance ticket booths located in the Esplanade between both parks. Keep in mind that you can only upgrade a park ticket if the ticket is still valid. Once a ticket is completely used and no longer valid, you cannot apply the value of that ticket to an Annual Passport.
I hope this helps, and please return if you have any other questions. Have a frightfully fun trip!
