Our friends at WDW News Today have some great pictures of Luxo, Jr. performing at Pixar Place in Disney's Hollywood Studios. According to the post, Luxo, Jr. actually comes out of an enclosed room and puts on a three-minute show up on what could be loosely considered a balcony or elevated patio. After some interaction with area music, he returns to his room.
I look forward to catching Luxo, Jr. during my upcoming WDW trip later this week. Maybe I can bring some photos and a review in my trip report. Stay tuned!
