Hi Yuhan,
Thanks for setting sail to planDisney with your Disney Cruise Line planning question; we are glad you're here!
Just like the tides of the sea, holiday plans change so let's see if we can get you on your way for some smooth sailing. To change the primary name, you will want to
call Disney Cruise Line and ask a Cast Member to assist with your name change. If your cruise has not been paid in full or you did not book a restricted fare, this should be no problem.
Since you have plenty of time before you depart, be sure to peruse the Disney Cruise Line website to discover all the
ways to prepare for your cruise. I always mark my calendar for special dates such as my Onboard Activity Booking Window and Online Check-In. These dates will depend on your
Castaway Club status. If your cruise includes stops at ports, you can explore the
Port Adventures offered. Since your cruise is quite a ways away, the complete list may not be available just yet, but keep checking the site for updates. I also recommend exploring your ship's deck plans so you are familiar with the ship's layout and then navigate the ship with ease once onboard. And of course, download the
Disney Cruise Line Navigator App to help with your planning before and during your cruise.
I hope this information is helpful to you, Yuhan. Please write back again if you have other questions; we are happy to help!
Wishing you many magical memories,
Shannon
