Hi Stacey!
You can get more information on the various Walt Disney World Dining Plans
here. Click on one of the PDFs on the right and then look in the back for a list of restaurants; both Table Service (full service) and Quick Service (like fast food in your local area) restaurants are listed.
The Quick Service Dining Plan provides 2 Quick Service meals and 2 Snacks per person per night of your stay. So if you are staying 5 nights, you would have 10 Quick Service meal credit and 10 Snack credits per person in your party over 3.
If you decide to go with a Dining Plan that offers Table Service meals, or if you decide just to pay for Table Service meals, be sure make an Advanced Dining Reservations (ADRs). ADRs can be made up to 180 days in advance and many Walt Disney World restaurants book up early. ADRs can be made in advance at (407) WDW-DINE or online
here. A couple of restaurants actually book up close to the 180 milestone.
Enjoy planning and write back if you have any more questions!
