GlowFest is a loud, music-filled, psychodelic celebration at DCA in the Hollywood Blvd/studios area, just to the left of Sunshine Plaza.
I don't know how often it happens but my family ran into a "show" on Wednesday night and my special needs 9 year old nephew LOVED it. As did many smaller guests who were out in the street dancing to Cher, Journey, etc. Everything is day-Glo colors including the Cast Member dancers and the alcoholic drinks.
I heard it can get a bit rowdy but we were there around 8:30 and it was fine. Lots of families and lots of teens by themselves but everyone was having a good time.
I recommend checking it out. We loved it but if you don't, it is easy to leave. It is just like a street party, not a sit down show or anything like that.
