I don't have pics and never went to a wedding there, but I did go there one night for swing dancing.... let me just say it is BEAUTIFUL inside just as it is! It's pretty big and if I want to say there is an upstairs level but don't quote me on it.
I only went the one time and hung out and watched everyone dancing in their 40's clothing.. it was so fun.
I bet with disney decorating it for a wedding it would be magical.
good luck and I hope someone has some pics!
