In terms of the AP holders, the big(gger) impact is going to come after August 16th, the last day of the SoCal and SoCal Select AP holder's summer blockout. There is usually a noticeable uptick the week after the blockout ends (especially on the weekend) as the SoCal and SoCal Select AP holders return to the parks for the first time since June. As others have mentioned August 14-16 is the D23 Expo, so there will probably some crowd impact the week leading up to the convention.
