We usually drive, so 6 days is all we can manage at a time. The rest of our 10 day trip is spent driving there and home. I am flying for the first time in Dec. But, unfortunately, not getting to enjoy a longer stay as we want to be home for Christmas. I am still getting my 6 days at the parks though so I can't complain. Especially since I will finally get to see all the Christmas decorations. Each time I wish it were more and I know this trip will be even worse. I know there will simply be sooooo much to see with all the Christmas specials that 6 days will simply not be enough. So if you can manage to be there 10 days, I say go for it.
