Just back, we went Wednesday the 20th of July and Wednesday the 27th. The 20th was the week after July 17th and it was a zoo. We did DCA most of the day and that was fine but DL was a nightmare. A week later we spent the entire day (open to close) in DL and we managed to ride every big ride (or hold a FP for it by about 2pm). We did not try to do Fantasyland but by 10pm the lines were down in there. The trick is to collect FP's as quickly as possible and to save them for later in the day (You can always use a FP after the return time has started we used ours hours later).
The crowd on the 20th was as bad or worse than anything I have ever seen at DL. I grew up down the street and have been there on July 4th, Christmas day, Thanksgiving week... this was worse because the crowd got there earlier than normal and it stayed bad all the way to park close. The 27th was not as bad but again the crowd was much thicker than we are used to by 10am (open to 10 was still pretty good, but it used to be noon before it got really bad) and there was very little thining of the crowds at night.
I do not go to DL in July/Aug very often, but I was there two years ago on July 8th and the crowd was nothing like this.
