I had friends there that time this year, it's the week of my son's birthday and when I had wanted to go, but I had a better deal a few weeks later. They had low crowds and waited very little for anything, still a few fastpasses for the big ones like Toy Story, TOT, Aerosmith etc..Usually with an hour return time though. They did get some cold weather though, and had to buy jackets and sweats they were packed for summer weather and freezing. But every year varies, watch weather down there just before you leave and pack some jackets/sweatshirts just in case!
