Hi Emily,
Great choice! Contemporary Resort is one of our favorite locations. Our boys love to watch the monorail travel thru the resort and we especially love the proximity to Magic Kingdom. Within the last year or so there has been some changes to Contemporary Resort's dining options. They recently moved their quick service location and added a new unique restaraunt called The Wave. They have now opened a new quick service location near Chef Mickey's called The Contempo Cafe.
The Contempo Cafe serves breakfast, lunch and dinner from approximately 6am to midnight. Breakfast choices include eggs, waffles and french toast, lunch offers flatbreads, made to order salads and sandwiches and dinner includes lunch options and addtional pasta choices. You can find information on the dining at Contemporary Resort
here. A great place to check for menus is at www.allears.net , choose the dining option at the top and then to your left select resorts. You will be able to select each Contemporary restaraunt for a view of their offerings.
Hopefully something will fit your children's current likes. A great thing about your location is you are just a monorail ride away from Epcot and Magic Kingdom which both offer a number of quick service locations. The kids will be happy to hear most of these offer chicken strips, hot dogs and burgers-the staple of my kids' diet.
Wishing you an amazing trip!
