Hey Howdy Hey Jessica and welcome to planDisney!
There are so many reasons that the Fall is a great time to visit the Walt Disney World Resort but
Mickey's Not-So-Scarry Halloween party in Magic Kingdom has to be one of the top! Thank you for your question about the tickets. I will be happy to give you more information on the specifics.
Jessica, you made a great choice choosing a travel agent to help you out for your upcoming vacation. They can be so helpful to do the heavy lifting and booking of things while you enjoy the fun of planning your vacation. In Discussing the ticket options with a Cast Member, they did let me know that when your agent goes to book your tickets for Mickey's Not-So-Scarry Halloween Party, they will have the option to either select "Will Call", "Virtual Tickets" or both. Virtual tickets will give you instant access to them on your My Disney Experience account and Will Call will have you stop at a Ticket Window or Guest Services to activate your ticket. If they were booked with Will Call, this is a super easy and quick step. The Cast Members can activate your tickets and have them available to your My Disney Experience account which you can access with your MagicBands, MagicMobile pass or they can give you a physical card if you choose.
Remember on the day of the party,
you can enter Magic Kingdom starting at 4 PM. This will give you a few hours to hop on a few attractions and save the formal party hours for special Halloween events such as trick-or-treating, parades and fireworks. There is so much to look forward to for this party and you can keep up with the latest developments over at Disney Parks Blog to best plan for your spooky event!
If you have any other questions, please feel free to let us know, we are always happy to help!
Have a Magical day,
Nick
