We went a couple of years ago.
We started at MGM. Walked through the Osbourne lights. Talked about the Christmas theming in movies and other things.
Went to Epcot. Discussed the different holiday traditions of other countries.
Went to GF and WL.
Went backstage to where they make the decorations and store them during the rest of the year. We had the chance to make a decoration the Disney way.
Were supposed to go to MK but due to weather delays, ran out of time.
I've read a lot about all the different tours, and we have done many of them. This tour has the most differing reports about it and it is seems to come down to the CM. It seems that, because it is only offered part of the year, you may get a CM that is not well trained. An example, you go to WL to look at the tree, our CM had all kinds of stories about the design etc. Very interesting. I have seen posts that their CM just walked them around the tree saying nothing.
