The thread you're referring to was discussing the resort as a whole. People were worried that the entire resort was going to be insane, which prompted someone to start a post explaining why things were really fine, and even easier than usual for most of the resort. It NEVER said that Carsland was going to be easy. Instead, it said that Carsland was going to be the only super crowded area, which was part of the reason why we didn't need to worry as much about the rest of the resort. I'm sorry you were disappointed, but maybe you just didn't the thread very well. BTW, 45-minutes isn't something to complain about at the parks.
Yes, I think the thread the OP was referring to my thread I created last month on the subject!

But yes, as you stated and I made VERY clear in that thread, I wasnt saying CL or RSR wasnt crowded, just the opposite. I said, as others stated as well, that due to so many people being IN CL the rest of the resort was lighter and more managable for that time of year. I think the way I titled it gave people the impression I was saying CL was a breeze when I was trying to say that the massive crowds people assumed would happen because of CL didnt gel as badly as it did! And I think this has proven to be true for the simple fact that the CM block out that was implemented for the entire summer was lifted the second week of July BECAUSE the crowds didnt show up as Disney anticipated!
So I think thats part of the increase crowding this month along with more vacationers in general coming in July, but I NEVER said CL and RSR was a breeze!
In fact, first line in the second paragraph in the post: "Seriously, besides RSR which has ridiculous waits for it and has to be a record of some kind, the rest of the resort feels darn near peaceful!" So I made it preeeeety clear RSR was busy and in other posts in that thread stressed that if you want to do RSR, show up EARLY and be prepared to wait! In fact, in my OP alone, I think I stated 5 times how crazy RSR is! But the point was the REST of the resort was fine just as long as you get there at a decent time and sometimes DL did not feel that busy at all on a Saturday out of all days. But again, I stressed in that thread that NO ONE should change their plans or ASSUME it was going to be super light, only more manageable than was expected, thats it!
And I also stressed while things were VERY good late June and early July as I experienced, I also said it could naturally change as I said in the first line in the fifth paragraph: "Now, summer just started, it can get worse fast"
So of course there were no guarantees and honestly, even now, while it has gotten busier, is still no worse than most summers! BUT I was there on July 17th like the OP was and it was busy! That was easily the busiest day I seen it all summer! Of course, part of it was due to it being the birthday! *I* was there specifically there just to celebrate the birthday so I imagine many had the same idea as me!

But I am sorry the OP ran into bigger crowds, but still sound like they had a good time!
But I wrote in that thread along with others that you should STILL be prepared by the crowds and I never suggested CL/RSR wasnt busy, just the opposite in fact. But not the nightmare people were predicting OUTSIDE of RSR!
