It seems like I remember when they did a press release about it that they said Dinner would be a character meal. I want to say they were going to have Lumier, the beast, Belle, etc. but I can't find the press release cause its been so long, so you can take what I said with a grain of salt. I'm just going from memory.
I forgot to mention that I also seem to remember the plan being that it would be a counter service for lunch and a table service for dinner much like the new Hacienda de San Angel in Epcot.
Well, I spoke to Belle just a couple of days ago - seriously, I was really talking to "Belle" about this - and she said that it will be a wonderful "show" hosted by Cogsworth and Lumier - so I am assuming in the audioanamatronic sense. However, that she and the Beast will be there to welcome their guests. So there are your characters. I hope this information helps!
