We had the quick service meal plan last year- one meal per person per night- while we never pay for the meal plans, we did find this helpful.
We just got the Fun n Sun 10% off for our upcoming trip this May- it only takes 10% off your room portion of your package- took $105 total off our room at All Star Movies (staying 6 nights). Our dates end before the meal deal. Honestly - I think the meal deal is a better value. If you add up what you might spend on that one meal per day quick service- it comes out more than 10% off our room for sure, and probably the suite too. And last year the meal plan was per night- we had an extra because we don’t normally go to the parks our arrival night or the day we leave. The quick service plan also includes a snack with each meal- or an extra side or something- we just put those in our backpacks for later. It definitely saved us more than the Sun N Fun deal does this summer.
