I had a friend (regular visitor) just in WDW. She said end of October was slower, but then the last two days of her trip it got considerably more crowded. Her last two days she said it was as crowded as she can remember it being for this time of year.HS today is rated a 5, but the actual almost always ends up being lower. The last few days have turned out to be 2, 3, 3.
I think it's possible we are seeing not so much a higher crowd effect but a snowball effect as more people realize G+ exists, and as more people buy it, and as more people start reading and seeing which rides go quickest. "Hey, you have to get SDD at 7am!" I think maybe at the moment it's kinda the same crowd levels, but more people are hip to the G+/ILL scene in general.
