Yes. That's the reason the first year of HHN ORLANDO was called "Fright Nights" because the higher-ups wanted to avoid bad press from the Hollywood incident that happened 5 years prior. However it would go by HHN in 1992-present.
The Hollywood event was known as Halloween Horror Nights in 1986 & only consisted of the Terror Tram. It wouldn't return to Hollywood again until 1992 (Orlando's 2nd year). Ironically, Terror Tram returned that year, BUT would not return again until the 2006 reboot which introduced "getting off the tram"/"walking the backlot".
The event itself didn't return for Hollywood until 1997-2000. No Terror Tram, only 3-4 houses & A LOT of entertainment. However in 2000, the event saw the FIRST & only SZ for Hollywood. Unfortunately, the event would go dark/on hiatus until 2006.
.....and that's what you've missed on Glee!
