Hi Westley,
How exciting to be traveling with your daughter on a Disney Cruise Line vacation! Thanks for sailing by planDisney with your questions; we are here to help.
As long as you have your daughter's
passport and it is valid for the length of your cruise, you do not need to bring a birth certificate or other identification for her. That is one of the great
benefits of traveling with a passport.
Children traveling with at least one parent do not need an
Authorization for Minor to Travel without a Parent or Legal Guardian. So, as long as you are traveling with your daughter, according to Disney Cruise Line policy, you are good to go.
I hope you plan to take a little "me" time during your cruise. While you enjoy a
Senses Spa & Salon experience, an
adult-exclusive activity, or just a peaceful moment at
Quiet Cove Pool or settle in with a good book at
Cove Café, your daughter will enjoy fun activities at
Disney's Oceaneer Lab or
Disney's Oceaneer Club. It really is a win-win!
I hope you have an amazing vacation, Westley. Please sail by again with other questions!
Wishing you many magical memories,
Shannon
