I would have said the second two weeks up until our visit this year. We always go in the last two weeks after the American kids have gone back to school. It has always been wonderful having the parks so quiet and walking onto the rides. Added to that the children loved going back to school with a Disney holiday fresh in their minds - what could be better?
However this year was something else! The popularity of the free dining plan meant the parks were very busy. (or at least compared to the low base we were used to)
Having met up with forum members who had been in Orlando during most of August they said that the first two weeks this time were less busy!! It seems that many people delayed their holidays until 13th August when the FDP was introduced. Certainly we had to make sure we were up early and at the parks at opening time - a change from all the previous visits when we could just trundle up to any park at our leisure. The restaurants were very busy too and ADRs were essential. I probably will continue to visit during these two weeks. Its just a pity its that bit busier now.
