The big difference with F&W and the DDP is you can use your snack credits at the booths. Some of the snacks are worth a bit of cash out of pocket (I think there is something on one of the menus for around 7.50 that you can use a credit for), so in that regard the snacks are a good deal. But definitely not a huge difference from the rest of the year.
I agree with Disney girl better at EPCOT with the Food and Wine Fest going on and you will be seeing me get the lobster roll and filets at Canada and Africa with the snack credits and lesser items paying cash or using my rewards card.
And DDP sam for everywwhere else except its free dining time now so it may be harder to get your favorite restaurant unless you book your ADR early.
I be using some of those snack credits thes coming Friday can't wait .
