Ahh--what a pain. I guess I'll just ask and see what they say. It's funny--I hadn't really thought about it before because we have always gone on DDP, but the child's price for F! is more expensive than just buying the meal at MM--I had not expected that to be the case. It can be the case for an adult meal, depending on what you order, but there are several options where the ala carte charge for your meal is equal to the F! package.
I guess I never saw it as "paying" for the seat. I thought of it as Disney's way of ensuring you are eating at a TS restaurant at HS and at off peak hours. Now that I looked at the kid's price, it's annoying that they charge more than the kids menu price. It really shouldn't cost more than is possible to pay ala carte--the adult's price isn't. Oh well!
