Two years ago we arrived at DL on Nov 09 and by Nov 11 all of the decorations were up and the HH and Small World were up and running with the holiday decorations. We found it to be a great time to go because the holiday crowds had not really started, last year we went on the 16-22 with Thanksgiving being the 23 of November and wow, the decorations were great, the weather was unbelievable and the crowds were there but what the heck it is DL all you need is a little patients!
