The Starlite drive-in in Holland and Saugatuck are one in the same. Best that I can tell, it opened on July 4, 1948. I could not find any other listings of it after 1987. A construction company seems to have taken over the site, with the snack bar/projection booth only remaining.

I was looking for info on the Starlight DIT in Saugatuck, and I ran across the following in a book called "Off The Record: The Unpublished Photographs of Bill Simmons: A Pictorial History of Saugatuck in the 40s and 50s." Page 84: "The Starlight Drive-In Theatre opened on the Blue Star (note: Old Highway 31), complete with windshield cleaning service, and another short lived drive-in theater with "room for 400 cars" was established at the north east corner of Center and Ferry streets in 1946 by two Chicago fellows by the name of Cox and Smith."
