It's quite Christmas-y...most of the decorations are up except the tree so far, and on Friday they actually start the Christmas parade and fireworks!
As for crowds, they have been pretty reasonable. On Monday at DCA most e-tickets were about a 30 minute wait if they weren't broken down.
Tuesday we were in DL and crowds were pretty moderate and DCA seemed pretty empty just after 5 when we walked through to the Grand but it was almost parade time, so crowds were probably there. Soarin had just a 15 minute wait.
Today we only made it for about an hour and a half and DL was pretty empty. We did PFF, Mr Toad, Carosul, Snow White, plus the street car down and back in about half an hour, went through the princesses again and had time to spare before the 1105 Rapunzel show.
It's a good time to go, but the hours are short and there's less entertainment during the week.
