The parade was born despite a disastrous rehearsal before their debut. WDW notes, cast members were getting shocked; floats were crumbling and some couldn't even make it to the end of the route. Not to mention, the OG floats weren't even all in 3-D like they are now. Thankfully, things appear to have smoothed out and improved over time.

Interestingly enough, the festival of lights is no stranger to relocation, as the Disney Parks Blog notes it started in Disneyland and showed there until 1996.
