Did you misread the OP, or did I miss an attempt at humor?
In response to the OP, park hours, fireworks, Fantasmic, etc. are maxed out during most of the month. The last 8-10 days often have some cutback in hours.
After about Aug 20 the AP blackout period lifts, so AP holders will come back in force. However, the typical summer visitors will be gone by then.
I have been the last two summers during the first week of August. In August 2005 it was more crowded than 2006, but in both cases crowds were manageable IMO. If you avoid weekends it is not too bad, especially if you can get to the parks early each day.
