Welcome Aboard, Therese!
A fantastic voyage on the Fantasy - how exciting! You're in for a real treat - the
Disney Fantasy is a gorgeous ship, with tons of fun activities and awesome Ports of Call. Looks like you're ready to start planning!
No need to bring your own Pack n' Play - portable cribs are available onboard. Just make sure to request a crib when you make your reservation! You'll also find high chairs waiting for you in the dining room if needed. Disney takes good care of the tiniest of travelers!
Disney Cruise Line allows two bags and one carry-on per guest. I suggest unpacking once onboard and storing your empty luggage out of the way - under the bed or in the closets. Underbed clearance on the Magic/Wonder is 9 inches, and 13 inches on the Dream/Fantasy.
Hope this helps with your planning and packing! Come back and visit if you have any more questions before you sail - we're happy to help.
