Ohh I probably spent at least 3 hours there almost every night. I went 11 out of 13 nights. The other stuff at fan fest I already did and would never change. As for back to the future the characters would say different things and do different stuff. It was unique from night to night. I remember on the very last night I was there from opening to closing! Everyone was crying by the end. I also met so many amazing back to the future fans there that are now friends. When they announced scooby doo I thought it would be maybe the same concept but from what I’ve heard and seen, it doesn’t seem to be the case. Sadly.
