We have experienced a consistent delayed opening of E ticket attractions at EMH rope drop this week, and it happened at each of the parks. They all opened 20 or so minutes later, closer to full park opening. If a full pattern had not developed, I wouldn't be so skeptical. Has this become a "thing" outside of the Christmas peak season? It really appears that they used the delays to disperse the rope drop crowds, which really took away the advantage rope dropping.
