Ahoy there, and welcome to planDisney Sherri!
It brings joy to my heart to learn that you’ll embark on a magical
Disney Cruise Line vacation with your granddaughters! I do not doubt that their most cherished memories will revolve around this incredible time spent with you during this cruise.
It is good news that your granddaughters will have their
original valid US passports, which will make things easier when checking in at the terminal and when you return and go through customs. Given that the children will travel without their parent or legal guardian, the parents must complete the
Authorization for Minor to Travel without a Parent or Legal Guardian form. This must be completed for each child traveling, and you will present the completed form during check-in at the port terminal. I hope this helps.
Please return and let us know how we can assist you further.
Have a magical experience with your granddaughters!
