Ahoy Manan!
Welcome aboard the Disney Parks Moms Panel. How wonderful that you will have the opportunity to set sail with your cousin and her family this summer. I am excited that you will be joining Captain Mickey on the
Disney Dream! The more pirates the merrier!
To get in on the fun, I recommend you
contact a Disney Cruise Line Vacation Planning Specialist who can help add you to your cousin's reservation. You will need their reservation number to help the specialist locate the reservation. If your cousin used a travel agent to book this adventure, you will need to reach out to that agent instead.
To add yourself to your cousin's reservation, there will need to be capacity in their stateroom for you. The Vacation Planning Specialist will be able to review your options in the event their stateroom is at capacity, including booking you a
stateroom of your own. Disney Cruise Line does not offer
single-occupancy fares, so if an additional stateroom is needed, the cost would be the same as two guests staying in one stateroom. A member of your cousin's family could always join you in your stateroom!
I hope I've steered you in the right direction as you begin planning your own adventure onboard. Cruise back to the Disney Parks Moms Panel if you have any additional questions before you set sail!
"Sea" ya real soon! Angie
