(As locals) This is why we avoid the parks on the weekends. We went to the Studios last night and had no issues with anything. We arrived around 3:30 pm ... Parked with no issues. Made FP's on the way to the park. Got Tower, RnR & Star Tours with no issues. Ate at the Tune in Lounge. Watched two shows of the lights. Out by 8:30ish.
Yes. The park was busy when it started to turn dark for those coming to see the lights. Though other than that ... Nothing out of the ordinary for this time of the year as far as crowd level wise to us.
