Ahoy there, William! Thank you for your question - we're so glad you stopped by!
It sounds like there's a big, family,
Disney Cruise Line adventure brewing, and that sounds like so much fun. I love going with extended family and friends on one of the
Disney cruise ships. They really do have something for everyone to do.
To make a payment on a cruise that you have booked, you can go to the top of the website where it says "Already Booked" and click the drop-down menu. You'll see the option there to
Make a Payment, which is where you would go if the other family staterooms were booked by you.
If the other family members' staterooms are not on your reservation list, you will want to
call Disney Cruise Line to make the additional payments. You'll need the stateroom numbers you want to pay for, as well as the last name of one of the guests in that stateroom, and a birthdate if you can get it. One of the cast members will be able to hook you up to make the payments.
If you are going to want to do things together, like book
port adventures or make dining reservations in one of the exclusively adult restaurants, make sure when you have the cast member on the phone you ask them to link your reservations together. This can be done online, but if you have them on the phone making those payments, it's a great time to make sure you're all connected and can make plans that include each other.
Have an absolutely magical voyage, William!
