Hi Debi! Welcome to the Disney Parks Moms Panel!
It sounds like you will be taking advantage of a
Disney dining plan during your visit. I have used the different dining plans myself many times because I love not having to think about how much I budgeted for meals and snacks while I'm on vacation, since it is already paid for in advance!
When it comes to exchanging meal entitlements, you are not able to upgrade a Quick-Service meal entitlement to a Table Service meal entitlement, but you can change a Table-Service meal entitlement for a Quick-Service meal entitlement. If you wish to do this, simply let the Cast Member know at the Quick-Service location that you want to use a Table-Service meal entitlement for your Quick-Service meal. Keep in mind that you get better value out of your Table-Service meals by actually using them at a Table-Service restaurant and you will want to make
Advance Dining Reservations for any Table-Service locations that you are hoping to try.
I hope this helps with making dining plans for your upcoming trip, Debi! Happy eating!
Tabitha
