Hello there, Desmond! Welcome to
planDisney.
Regarding your question, I spoke to a Cast Member and there is no way to modify the people in your party for your
World of Color Dessert Party reservation. And in order to enter the Dessert Party area, everyone on your reservation must be present. I apologize if this was not the answer you were expecting.
Sadly, I recommend canceling your reservation to avoid being charged. There is a 24-hour cancellation policy. The full price of the party will be charged if a Guest cancels within 24 hours or is a "no-show" for the reservation. If you decide to book the party again after the cancellation, you can try doing so
online or on the
Disneyland Mobile App.
Desmond, did you know that you can try to get a
Virtual Queue for the preferred viewing area for
World of Color - ONE? It is an excellent option for Guests that do not have tickets for the
World of Color Dessert Party.
I hope this information is helpful to you, Desmond. Feel free to visit us again with any other questions you have. We are always available to help!
Your Pal,
Alejandra
