Hey there, Chesney! Thanks for swinging by planDisney with your question. A very warm and magical welcome to you.
Chesney, currently you cannot add Guests to a dining reservation in the
Disneyland mobile app. However, if someone in your party arrives for the reservation before you, no worries, they can give your name to the host stand and begin the check in process for you.
I bet you can’t wait for your visit to the Happiest Place on Earth!
The Holidays at the Disneyland Resort are so bright, festive and magical. World of Color – Season of Light and “it’s a small world” Holiday are two of my favorite attractions this time of year. The thousands of twinkling lights will fill your heart with holiday cheer.
Have a wonderful time and happy holidays to you!
