Is tomorrow 2/5/20 a good day to go. Will it be very busy?? What are the not very busy days?? Will there be a parade and fireworks?

Historically tomorrow should be fairly low, today doesn't seem too busy. Galaxy's Edge definitely changes that though, busier than expected. No parade tonight, so I don't think there will be one tomorrow. There is a fireworks show at 8:15 though.

It will be moderate, so go early and be inside the park at opening. The lines are shortest then.
