Well, if your dining plan is free, does it matter too much that the last few credits have not been used? Obviously if you have paid OOP for it, then I would definitely try to use them, but otherwise, I think I would just let them disappear.
I have to say, DVC is a blessing in that sense, because we aren't stuck to the stupid plan, that is getting less and less value for money each year anyway. Yes, we have ADRs for most nights, but because they are places we want to go as opposed to places we have to go 'to use up the credits'. We also won't eat anywhere near the
DDP snacks and CS values.
Some people have also had luck in getting the TS credits knocked down to CS credits, which means you could do a breakfast at the resort. Otherwise, like someone else said, if you want to use them up try the resort restaurants, DTD and Boardwalk. It's the park restaurants that fill up first and fastest, as people don't want to leave to eat and then come back. I would imagine the MK resorts would be almost as busy as the parks too, because of their close proximity. Try somewhere like Boma, which is miles away from the parks, yes, but will also be quieter
