Greetings and welcome to planDisney, Timothy. Thanks for stopping by to share this question with us.
Oh dear, I'm terribly sorry to hear that one of your family members is not able to join you during your visit to the Disneyland Resort. When it comes to multi-day
theme park tickets, once the ticket has been scanned and used by someone, it is now assigned to that person for the entirety of the visit and cannot be transferred to someone else. If you have a
wholly unused ticket, you can certainly have someone else use the ticket in place of your family member, however, the ticket must be used by that one person for all three days.
I hope this helps as you're planning for your visit and I hope that you have a wonderful time with the other family member who will be joining you. It's a great time to visit the Disneyland Resort with the
Disney100 Celebration in full swing. The resort is decked out in platinum and purple decorations, there are festive eats and two new nighttime spectaculars. I highly recommend checking out both of them.
Wondrous Journeys in Disneyland Park was my favorite.
Timothy, if any other questions come to mind as you get ready for your visit to the Happiest Place on Earth, please come back to ask us. Until then, I wish you happy planning!
Michelle
