Hi Tammy!
You found the same problem I first encountered when trying to book my first Disney Vacation! It's easily fixed.
When you are on the home page for
Walt Disney World, there is an option for planing your vacation on the left side of the main screen. Click on the "Price Your Vacation" tab and fill in the information, making sure that you select "Packages".
When you are transferred to the next screen which includes your basic options, there is a tab for adding flights. Click the tab, add in your information and the search engine will go to work putting the final touches on your complete vacation package!
Be sure to look at all the other options available as well including the different room types and views, dining options, ground transportation and theme park and water park options!
You can put together an incredible vacation package with all the bells and whistles to make your unforgettable vacation and epic memory!
Have a magical time.
Carrie
