There was a post about this topic on the general park touring board. Mom2Rtk posted a lot of good information on photographing in Enchanted Tales With Belle, try sending her a message. I would have some info but I was busy playing a suit of armor.
....... and we're all still waiting to see the photo!
Here are some of my random thoughts on photographing ETWB:
1) Be prepared for a variety of limitations from CM's. My first trip through I sat, but then got up and moved around the back and side of the room and didn't even get a sideways glance from the CMs. The second time through they said I could stand but had to take a back row seat and stand from that seat.
From a back row seat, I got WAY too many heads in my shots. My preferred seat would be toward the back but on the inside aisle.
2) The lighting in that room is quite variable. When Belle poses at the end for photos with the participants (she only does photos with participants) she has great stage lighting, so the lack of flash isn't a problem. As you take photos of her interacting with various participants though, some will be in far worse lighting.
3) If you can, shoot RAW. It was nice to have maximum latitude to adjust exposure and white balance.
4) I really wouldn't want to be tied into a fixed length lens in here. I shot the following back behind the photopass photographer and still shot at 17mm. I cropped a little,but not much. EXIF: f/5.6, 1/160, ISO 1600

5) If you hang back, you can get a photo with the wardrobe. The "no flash" rule is pretty limiting though since it is not lit for portraits. But if you do hold back, be prepared for a very limited choice of seats when you get to the library.

6) When taking photos of Lumiere, either turn down your exposure compensation, or use spot metering on his face so you don't overexpose. Your camera can misinterpret all the darkness in the shot and overcompensate.

7) I used a variety settings trying to find the right one. But I do agree that the flexibility of having a bit of zoom, along with a 2.8 aperture was very helpful. I used my Canon 17-55 f/2.8 for most of these shots. But I did swap out for my Canon 10-22 f/3.5-4.5 for some shots as well. That was just for experimenting though. I would have been totally fine just sticking with the 17-55.
