Ahoy, Leia!
Welcome to the Disney Parks Moms Panel! Your final countdown is on with less than a month to go until your magical voyage with
Disney Cruise Line! It really won't be long now before you're enjoying everything Disney as to offer at sea for Guests of all ages.
As you plan what to bring, you'll be happy to know that your little ones can have a carry-on bag or backpack. My children always have a bag of their own that they are responsible for when we travel. They always bring a few things that help keep them busy while we wait to board the ship. Staterooms will be ready at 1:30, so I always make sure the bags are not too heavy in the event that we board earlier than that time.
As for your other question,
wine in a box can be brought onboard as long as it is packed in your carry-on luggage and is 750ml or less. Since your box or "brick" is equivalent to two bottles, it does not fit those requirements. It must be an individual box equaling 750ml. Hopefully you'll be able to find some Bota that will work.
Leia, we are so glad you cruised by to "sea" us at the Disney Parks Moms Panel. We hope you'll write back if you have any other last minute questions. If not, best wishes for a vacation filled with pixie dust!
Have a magical time!
Nancy
