If you go to disneyworld.com, you can look up all upcoming events there.
Christmas @ WDW is awesome. There is Mickey's Very Merry Christmas Party @ MK. The park closes at around 7 or so & you buy an additional ticket for about $25-$30 (I believe) to come back in for about 4-5 hours. Most of the rides operate, there is snow on Main Street, Santa, hot chocolate & more. EPCOT has celebrity storytellers & Christmas Around The World. MGM has the Osborne Lights. Much more info available at teh site above.
As for Super Soap Weekend, it is at MGM from Nov. 9-12 this year. The ABC soap stars come out for autographs, parades, talk shows (live), games & more. It is a BLAST! You can keep updated on that via the site above as well or at abc.com
Hope this helps some! Good luck! Need more info, just let me know.
