Mid-November is when most are completely done. I remember back in '01, we were staying at POR. We walked through the main lobby area at the end of a long day in the parks. It was not decorated at all...the same as if you were there in July. Well...the next morning, we walked through to get breakfast before heading to the airport.....there was a huge Christmas tree in the center of the lobby and the entire place was completely decorated for Christmas!! It was mind boggling.
