Hi, Joseph! Welcome to the Disney Parks Moms Panel and thanks for bringing us this great question! I certainly understand how plans can change at any time, and Disney is great about helping guests make the most of their vacation by accomodating changes as much as possible. Hopefully yours can be worked out because extra family and friends means extra magic!
Most changes to resort reservations can be made online by pulling it up in
My Plans. If you rather, you may
call the Disney Resort Hotel Reservations line to have a Cast Member assist you. Please keep in mind that there are restrictions on the number of guests staying in a room and there may be an added charge for having more than two adults in the room. Also, changes to resort reservations must be made by a certain number of days before your check-in date to avoid additional charges. This very important date is going to depend on if you have booked a room-only stay or have a
Disney Resort Hotel Package. Changes or cancellations of packages must be done at least 30 days in advance, while those for room-only reservations must be done five or more days in advance.
Joseph, if you have already made your dining reservations, be sure to also modify them by adding your new guest. I have had some success being able to add just one more guest upon arrival at the dining location, but occasionally they have not been able to accomodate the change.
Thanks again for stopping by, Joseph, and please let us know if you have any other questions!
