The most bang for your buck meant two things for us last Aug when we had
free dining....being stuffed or sharing! You could get sooooo much food at times, it was unreal to us! If we were a fam with kiddos and would've stayed for a longer time, we could've shared and maximized most credits. We were only there for just over 3 days and have never seen sooooo much food!
Cosmic Rays - 1/2 Rib 1/2 Chicken platter, large pop, dessert -

This was already mentioned but man o man, could EASILY share this one! I get it thinking, heck, we're on free dining and I'd never buy it OOP. It was very good but I didn't want to eat the rest of the day and I barely put a dent in it! Looking at the menu and being there before,
Flame Tree BBQ in AK has the same platter option and you could maximize your credits there too.
Wolfganag Puck's Sit-Down DTD - We actually never ate here. We cancelled our ADR that morning because looking at our schedule and what credits we had left, we knew we would be over stuffed eating there. We choose to squeeze in 'Ohana's b-fast on our last morning instead. But we had our menu all planned out to eat at WPs and the total per person would've been over $50 each. We might try this place on our March trip if we do
DDP.
For us the DP works well for CS meals because I bring my own b-fast bars and drink coffee from our mug (no resuable mug debates please, I confess I'm a reuser, even though DH usually always buys a new mug each trip). DH loves a good b-fast so he can use what would've been my b-fast credits for lunch along with having a hearty eggs/omelet/waffle type b-fast each day. Everyone is happy. Also, because we're already getting enough food at the meals, we use our snack credits for beverages or share a sundae when temptation calls.
