The colorful decorations that were put up in Sunshine Plaza and the Hollywood Pictures Backlot are for California Adventure's new street party called "Glow Fest." This will be starting on Friday, June 11th, along with World of Color. The party will have music, dancing, and colored lighting. There are also going to be a couple bars added that sell themed drinks.
According to the OC Register:
"Disney officials said the live entertainment is meant to complement the World of Color show and provide park visitors something to do at night while waiting to see the show — or after seeing the show. People waiting to see World of Color can attend Glow Fest before and after the show."
I'm kind of curious to see how this Glow Fest turns out and if it helps with crowd control for World of Color. I guess we'll find out soon enough! June 11th is this Friday!
