Hiya Young! Thanks for sailing over to planDisney with this great question!
I'm happy to hEAR you are planning a vacation aboard one of the amazing
Disney Cruise Line ships! Each one is special in its own way and you are going to have a magical time during your voyage.
One of the best aspects of choosing to sail with Disney is the
modifications you can make to your reservations. I'm sorry to hear that one of your family members may be unable to join you on this trip. If this is the case, you are able to take that Guest off the reservation prior to final payment without any penalties. After final payment or within a certain number of days before you set sail, you may be subject to a change name fee.
To add or remove Guests from your reservation,
log on to your account and select "My Reservations". If you have any difficulty, you can also call our Contact Center at (800) 951-3532. A Cast Member will be happy to assist and make any necessary changes.
Young, one thing to consider is if you booked a concierge stateroom or in a category with restrictions, cancelation fees may apply. You should have been made aware of this upon booking your reservation and it should state this in your confirmation email.
I hope you have a magical time during your trip!
Stop back and see us again at planDisney!
See ya real soon!
Greg
