Heigh-Ho Amber,
This is a great question and one I can help you with.
Guests, who have a Room-ONLY reservation can easily speak to a Cast Member, in Resort Reservations by calling (407) 939-1936, and add the additional Guest to their current reservation. Be aware you will accrue an additional cost for adding another Guest to the room reservation. With Room-Only reservations, Guests can purchase and customize their Walt Disney World tickets to best create their Practically Perfect visit. Walt Disney World tickets can be purchased online and linked to a My Disney Experience account for easier manageability.
Guests, who have purchased a Walt Disney World vacation package and wish to add a Guest, should know all Guests on the reservation will abide by the same terms and conditions of the
vacation package or special offer. In other words, if your vacation package or special offer includes a specific number of stays and days and tickets, everyone on the reservation will be included no matter when they are added. Special consideration to those added later is not an option and does not exempt them from the terms and conditions.
As you continue planning your Walt Disney World vacation feel free to reach out to
planDisney for further curiouser and curiouser inquiries. We love helping our fellow Guests and can provide a wealth of pixie-dusted expert advice for any question you may have.
Have a Practically Perfect Day,
Amy M.
