How DL handles the night parade pre fireworks is pretty genius. They time the parade to exit Times Square 15 min prior to boom time. So that significantly slows entry to the park during that time. They also block entry from the parade corridor, only TL, and AL have entry but from those enterances you are funneled down MSUSA and not into the hub so the masses who watched the parade by itasw can’t get to the hub (there is not enough time to route to the other side of the park and get back.). If MK were to block access to the hub from FL and AL they could achieve the same goal. Meanwhile from the enterance they could funnel people up the auxiliary enterance and into TL. Meanwhile parade watchers in the hub and on MSUSA, pivot to watch the fireworks.
