Why not buy a Disney gift card for the amount you would spend on the dining plan and buy what you want, where you want? When I don't get free dining, that's what we do. I don't have to worry about where I want to stop and I can get an appetizer, dessert or both.
DDP is more of a convenience for me than anything so a gift card does the trick. Unless DDP is free of course. BTW, I ran out of snack credits during F&W....to many samples to try!
