I think it would be a failing if this was not a character meal. Even if it was as simple as meeting Belle and the Beast prior to dinner for a photo op (a la Cinderella's Royal Table or Norway). They would welcome you to the castle and then you would have your dinner. They don't need to have other characters then roaming. The only characters that would make sense to roam would be other princesses (like they do at Cinderella's Royal Table) and i don't think they need another "princess" meal, especially so close to Cinderella's Royal Table. The only way they do another "princess" meal is to end the run in Norway (which I don't see happening, because two in one park makes no sense and have the meal in Norway draws families to EPCOT). The only other way I see them having another "princess" meal is if they use different princess (ie the non-traditional ones you see at Norway or the Royal Table) They could have Mulan, Rapunzel, Tiana, etc. This would make it a different experience than the other two. That they may consider as the 'Princess" meals are big sellers, but the key is it needs to be DIFFERENT.
