Here are your current B&B meet and greet options during regular (non Christmas party or Halloween party):
EPCOT
Belle Blue dress--- daily in France on the side by the water. Regular meet and greet with autograph's and photos and a chance to talk to Belle
Belle Gold Dress---- Akershus meal--- unless there is a last minute substitute (i.e. Bell gets sick) she meets at the front for the formal photo after you check in. You can get autographs and they will let you snap a photo with your own camera. Hit and Miss as to whether you will be rushed- depends on the photographer. We have been there when DD got to talk to Belle for a couple of minutes- and we have been there when the photographer was pushing kids through so fast that they barely had time to pose (one time it was so blatant that Belle got mad). More often than not, we have had a good interaction though.
MK
Gaston-- out in front of his tavern daily- Regular Meet and Greet. He is usually quite funny.
Belle Gold Dress-- Enchanted Tales with Belle--- Definitely a must for a 5 year old B&B fan. Great special effects; you will see Lumiere and the Wardrobe; the kids can take part in a little play; and after the play the kids are run through a line to meet Belle and get a photo. However, this is NOT a regular meet and greet. You can not get an autograph, and unless you are positioned just right when your child goes through the line (or you are lucky and have CMs that let you move to the area, you won't get a photo with your own camera. I have seen parents try to get up from their spot on the benches to walk over and get a photo of their child with Belle and be told by CMs to sit back down. It is also very rushed-- there is no time to talk to Belle other than to basically say Hello and get a quick photo. Also, if a child is on the shy side and does not participate in the play, you need to be sure and have them line up for the photo-- sometimes CMs will announce or go get the kids that did not participate, but other times, they don't do that.
Beast- only at Be Our Guest dinner. We really enjoy meeting him though.
It is really a shame that there is no way to have a regular meet and greet with Belle where you get to talk with her, get her autograph, and snap your own photos outside of having to book a meal at Akershus. We were hoping that would change by now as I know many people complained when the new Fantasyland opened and she could only be found at ETWB for what I would call "partial" meet and greet, but it has been a few years now and nothing has changed. Beast hasn't met with Belle at EPCOT since BOG opened, and it doesn't surprise me that have not brought him back- but I really thought they might get Belle back out there somewhere!
