I'm hoping they open the parks a little later for Father's Day weekend, but I understand they need to deep clean everything and still allow time for employees to get home to their families. I am thankful that they decided to open until 7pm, because when they first opened, we were only looking at 5pm. We're coming, and thrilled, regardless. But, yes, during a typical summer you get a lot ride time out of a day - and most of that in the evening, when it's cooler, and a lot of the younger park guests have left.
Btw, looks like curfew has been lifted.
