I LOATHE Free Dining!
To me, it does nothing but guarantee no availability at restaurants. The ones that cant get to use their credits for table service, due to being booked solid, will then spill over to counter service which then leaves me to deal with large crowds at Cosmic Rays, Caseys, etc. Plus the crowds this type of offer generates makes it chaotic for ride queues, using Disney transportation (monorail, ferryboat, buses) etc.
My wife and I split all of our meals as we're not big eaters. We can afford to buy our own plate, but do not want to waste food. DD5 usually eats snacks or something light as she normally eats from other places outside of the restaurants we dine at. 40% off a Deluxe will save you more than paying for food. This is how much we saved last year: (copy & paste from older post)
Using the AP rates, the cost for all 3 of us per day is $100.00 ($33.33 each). We can't eat $100.00 of food per day....it's simply impossible for us to do that. We do all the signature restaurants, splitting meals, and we spend way less than that each day. Remember that this is only for 2 adults and one child so that's why for MY FAMILY it's not worth it to do FD or even deal with the hassle of FD crowds.
