Hi Haley,
I would be delighted to help you with your question about the Disney Dining Plan. There is a wonderfully long list of restaurants participating in the Disney Dining Plan at Walt Disney World
here. Once you click on the link, select the Disney Dining Plan you have booked for your March 2012 trip from the list under "Related Resources." A pdf file will download. You will find the list of participating restaurants within this document. For instance, if you chose the 2012 Dining Plan, you will see the list of participating restaurants on pages 4 and 5 of the document.
Once you decide where you wish to dine, call (407) WDW-DINE to make your advance dining reservations. I find this even easier than booking your reservations online. It's always nice to have a Cast Member on the line to suggest alternative eating establishments or dining times if your first choices are not available.
Don't hesitate to let us know if you have any additional questions about the Disney Dining Plan. My family uses the plan frequently when we travel to Walt Disney World and I would be happy to share whatever information you need to make your first Disney vacation as magical as possible.
Best wishes!
Jill
