We have a family trip to WDW planned over Christmas, but we might be cancelling it to go skiing instead . I'm thinking of taking a solo trip sometime this fall, or possibly asking my sister (who has never been to WDW and can't understand our obsession!). What is the best Oct./Nov. time to visit? Is the week after Thanksgiving especially uncrowded? (would love to show my sister the Christmas decorations). Also, my sister is a large lady - where is the site that explains what rides work for large people? Thanks for any help!
