Ahoy there Sylvia, and welcome to planDisney!
Plans do change sometimes, so I'm happy to share that you can
change your reservation. You will need to sign into the
Disney Cruise Line website to access the Already Booked tab. Then, click on My Reservations and select Modify Reservation. Not only can you modify the date of your selected sailing, but you can also modify your travel party and stateroom.
If you booked airfare directly with Disney Cruise Line, you will need to
contact them. I suggest you also contact Disney Cruise Line directly with questions about fees so they can pull up your reservation, and you both can discuss your specific details.
I hope you can get your reservation changed to a new date so you can enjoy all that Disney CruiseLine has to offer. If you have any other questions,
planDisney is here to help.
Adventure is out there!
