November is a wonderful time to go. The weather is usually between 70's to mid 80's with a little bit of rain (last year 2 days but didn't last more than 3 to 4 hours). Several things including Food and Wine Festival at Epcot through mid November and Super Soap Weekend at MGM. Only thing is that the parks (Epcot excluded) close early; however, you'll be at the BW and can enjoy the activities there.
