Not all the character meals are 2 credits, as a matter of fact I *think* only Cinderella Castle is 2. Askerhaus, Crystal Palace, Chef Mickeys, 1900 Park Faire are only 1 credits.
I have not been to Le Cellier in quite some time, so I don't know if they have changed to 2 credits. On the WDW website when you are making your plans I believe it will tell you how many credits are needed from the dining plan.
HTH,
