Hi Bilynn,
I am so happy to help you continue to plan your Disney Vacation Club Walt Disney World vacation!
If you add a Disney Dining Plan to your Disney Vacation Club reservation, this will be included on your Key to the World Card. Please note that you must add the Dining Plan to your reservation no later than 48 hours before your check-in date. The easiest way to do this is to call Disney Vacation Club Member Services at 1-800-800-9800 and the cast member with whom you speak can assist you with adding a dining plan to your reservation.
As for theme park tickets, I spoke with a cast member at Disney Vacation Club Member Services who let me know that if you want your theme park tickets to be included on your Key to the World Card, what you will need to do is to purchase the tickets when you arrive at the resort. By purchasing your tickets at the resort, they can be added to your Key to the World Card. If you purchase them ahead of time, you will have a separate ticket for theme park admission. If you decide that you would like to purchase your theme park tickets ahead of time, you can
buy your Disney theme park admission online. Once at that site, you can sign in as a Disney Vacation Club member to see if there are any discounts available; however, at this time the only discount that I am aware of is for Annual Passes and Premium Annual Passes.
I hope that this information is helpful for you, Bilynn! Please do not hesitate to ask if you have any further questions.
