Hi there, Bethany!
Great question! If you choose to use 2 of your adult Table Service entitlements from the
Disney Dining Plan for pizza delivery, you will end up with extra kids' credits left over on your plan. You could either order another pizza package for 2 more adult entitlements, or you could use the kids' Table Service entitlements for Quick Service meals and bring those meals back to your Resort hotel room the day you order pizza.
I have found that using Table Service entitlements for pizza delivery is not the best use, cost-wise. We ordered pizza on one of our big family vacations and there were 8 of us. We went ahead and just paid out-of-pocket for pizza because there is so much value in using the entitlements at some of the amazing restaurants that are on the property. As an example, if you dine at
Chef Mickey's for dinner one evening, the cost can range from $30 to $59.99 per adult and the kids' prices are a little more than half that. You would only need to use one Table Service entitlement per person to pay for that meal, so you can see where that value is.
I hope this helps with your decision, Bethany! Please don't hesitate to write back in if we can help with any other questions you have.
Wishing you and your family a Pixie Dusted vacation!
