Hi Christine,
Welcome to planDisney! A Disney World vacation with friends and family is extra magical, so Disney World makes it super easy to share your reservation information and plans. Regardless of who books your vacation, you can make payments on a reservation or add fun plans to your trip as long as you are linked as
"Family and Friends." Your cousin will need to log into their My Disney Experience account and you to their "Family and Friends" list. They will also need to add you as a guest on the reservation if they have not already done that. Once you are connected you should be able to see the reservation details including any remaining balance and make payments before you arrive!
Making a payment on your Disney World vacation is simple. You will log into your
My Disney Experience account on a desktop browser and navigate to "My Plans." This is located under the My Disney Experience drop-down menu at the top right of your browser. After you have clicked "My Plans," look for your reservation number. There should be a "Make a Payment" link visible next to your reservation number if you can make payments online for your reservation type. If this link is not visible, I recommend calling
Disney Resort Hotel Reservations. They can assist you with any issues including making payments on upcoming vacations.
If you end up calling to make your payment, that is also a great time to add any room requests you may have to your reservation. I always like to make sure I am close to the lobby or transportation because it makes getting to the theme parks super quick! It is easy for them to add these requests while you are on the phone.
Happy Planning,
Jenna
