Ahoy, Rita -
Welcome to the Disney Parks Moms Panel and thank you for logging in a question. Your February voyage will be here soon and i can't wait to have you and your family experience the Disney difference when it comes to sailing the high seas.
Since you are on the late dinner seating right now, you are still able to make a request for a change. The Disney Cruise crew wouldn't want your little one's sleeping schedule majorly disrupted, so I'm sure they'll try their very best to work with you and make things comfortable. For now, I would put in the request with the Disney Cruise Line Travel Desk, so that they'll have it on file for you. You can call them directly at 1-800-951-3532. They may not be able to give you a guarantee of the dinner schedule request right now, but they'll have it noted.
On embarkation day, you will definitely want to see the restaurant managers to reconfirm if they can make the change request. Check the Personal Navigator, or inquire with Guest Services on where the restaurant managers are setup for that afternoon. There will usually be a few people trying to make dining changes and arrangements (from rotations to adult-exclusive reservations), so you'll just need to spend a few minutes to take care of this when you first board. The restaurant managers will have their computers in front of them to try and make arrangements on the spot for guests. If your dinner schedule changes, the restaurant manager will also give you brand new Key to the World cards that will reflect your new dining assignment and rotation.
Let us know if we can try and answer other questions to help you plan for your cruise, Rita. You might want to reserve some Nursery time for your little one --
parents can have a lot of fun on the Disney Cruise too!
Have a great day!
