I know there are 2 threads going on about this, so if the Mods want to merge, go for it.
To us, the 2 credit meal is not so completely about the cost either, but also about NOT getting an opportunity to eat somewhere else. Dining at Disney is somewhat just as much fun as the parks. And each year we have a short list of locations we just couldn't fit in—be it time, location, or not enough credits. Now, if you are taking 2 credits up for certain locations, then that is another location I am NOT visiting. Yes, I could pay OOP, but I'm not fond of doing both OOP and DP—too much to keep track of already.
