Reading through your replies is like a rollercoaster!

I'm so easily swayed, first I want to, then I don't!
No, we don't have APs - this will be our first trip to WDW, maybe our only one ever and certainly our only one for a long time to come.
Having credits left over to save is no problem for us, and I don't mind getting some bits to eat on the long journey home
But if it would be a waste of money because of huge portions that we wont get through, then I'm not so sure. I'd rather buy less and let my children share. But then they're pretty unpredictable, one day they'll share and the next they'll all be ravenous!
Savings of $13 on just that day plus I still have my refillable mug
Seriously, we're not fussed about sit-down meals. With 4 smalls and my husband it's more stress than it's worth half the time (yes, even at places designed for children), and I *really* don't want to have to add in stress of getting places in time.
scboyd, thanks for your input, it's good to hear that it's not all fast food. Is there anyone else with experience of QS out there?
jamminmd - it's things like the turkey leg that puts me off! I want to try these treats, so will resent having to pay for them on top of already paying for the QS.
But again, if it saves me worrying about how much money to save and how much to spend, it could be a good thing, because at least then I'd have money to spend on treats like Dole Whips and a Turkey Leg!
