What was the Production Studio Tour at Universal Studios Florida like?

I heard that Universal Studios Florida used to have a studio tour which was like a more minor version of the one at Universal Studios Hollywood called the Production Studio Tour, and that it opened with USF on June 7, 1990 and (according to Wikipedia) closed in 1995. Wikipedia also says it was a tram tour of the USF park and studio. Doers anyone know anything about the complete ride experience of Production Studio Tour? What exactly was it like? Did it go near the soundstages, Swamp Thing set and Bates Motel/Mansion sets? Where was the entrance, queue and boarding area? Were did it exit? Why did Universal close it? Answers, please!!!
