Hello Yunseok!
Welcome to planDisney! Congrats on your upcoming trip to
Walt Disney World! I'm glad you are already set with tickets and your accommodations! Now you just need to connect with your family!
If you have access to your
My Disney Experience account, you should have your tickets and anything else you booked viewable. It will be here that you will look to connect your wife's account to your Family & Friends List. Look at your Friends & Family list and scroll to find the option "+Add a Guest." You can add your wife by entering her name and age and connecting to her. She will have to log into her My Disney Experience Account and accept your invitation. Once you are connected you will be able to assign a ticket to her and make plans with her.
If you are able you should download the My Disney Experience mobile app. There is a chance it won't be downloadable until you arrive in the United States but it will be very helpful in entering the Parks and making any reservations. You and your wife could work together to make plans for each other to have a great day! I'm not sure if you will be able to purchase a discounted MagicBand or MagicBand+ through her account as it is not offered to international guests but you can find beautiful ones once you arrive in the Parks. I highly recommend visiting
Disney Springs and visiting the World of Disney which is one of my favorite stores. Just a tip, I sometimes find my favorite souvenirs from the Walt Disney World Resort Hotel's gift shops. Maybe consider a detour using complimentary Disney Resort Transportation if you are looking for something special.
Since you are arriving during a special holiday time I would recommend speaking to a travel agent about purchasing tickets to
Mickey's Not-So-Scary Halloween Party! It's a specially-ticketed event on select nights in
Magic Kingdom Park. There is an amazing parade, shows, and nighttime spectacular. You are allowed to come dressed in costume even as an adult and get free candy! It is one of the best events of the year!
I hope this helps and let us know if you have any more questions.
Happy Planning!
