Hi, Lorraine!
I just love planning a Disney vacation. Now the countdown begins until your magical visit to see Mickey!
If your vacation is planned for 2017, you can add on the
Disney Dining Plan as part of a
Magic Your Way vacation package that includes your resort room and theme park tickets. A "room only" reservation does not allow you to add on the Disney Dining Plan.
However, I am guessing your holiday is planned for 2018. In this case, vacation packages and pricing are not yet posted. To book past 2017, you can only book a "room only" reservation at this time. Once 2018 prices are posted, you can convert your "room only" reservation to a Magic Your Way vacation package by adding on theme park tickets and the Disney Dining Plan.
Keep checking at
Disneyworld.com for 2018 pricing, and once it is available, call Disney directly at (407)934-7639 to have your reservation modified to your desired vacation package. Be patient, as it may be another few months until the 2018 rates are available.
I hope this all works out for you and that you can book a practically perfect holiday for your family!
Cathy
