In 2002, I went the weekend before Thanksgiving and it seems most all of the decorations were up(comparing it to December 2003). However, none of the Christmas-type "activities" start until on or after Thanksgiving-Osborne Lights, Candlelight Processional, Holiday Storytellers, Tree lighting ceremonies, etc. And I can't remember Christmas music playing in November as it did constantly in December(can't hear Manheim Steamroller now without thinking of WDW).
