Hello Amanda! There are several dining plans available to choose from. It sounds like you may have the Basic Dining Plan where you have one table service, one quick service and one snack for each night you stay at Walt Disney World. (Example: if you are staying five nights, each person will have five table service meals, five quick service meals and five snacks available.)
The Quick Service Dining Plan does not include any table service meals. If you were on this plan, each person in your party would receive two quick service meals and one snack for each night of your stay. Each person in your party would also receive a refillable mug to use during your stay.
I think it's great you were able to secure a reservation at Chef Mickey's - that is a fun place to dine. If you are having problems finding other character reservations please know there are many non-character dining experiences you can enjoy. A couple of my recommendations are Whispering Canyon Cafe for dinner, 50's Prime Time Cafe and 'Ohana for dinner - so definitely check those out!
I'm not sure if you know but you can search for available dining reservations
here. If you need additional assistance, you can call 407-WDW-DINE.
I hope your vacation is truly magical! Diane
