I heard Kissing Tower was also closed for the season. Storm Runner is expensive to operate due to the hydraulic launch, Kissing tower is a long ride where you're in an enclosed vehicle with a large group of people.
I can see with Sooperdooperlooper because its and older ride, so the queue space is smaller, making it more difficult to properly social distance and might be capacity and demand based. A little surprised Cupfusion has the go ahead. I haven't been since opening day of 2017 and plan on going late next month so it's just something I haven't done yet (along with the Triple Towers, Trailblazer, Sidewinder, Fahrenheit, Wild Mouse, and obviously Candymonium in terms of major stuff).
Sure, Storm Runner and SDL could be suffering some issues too, but I think what I said could be more accurate.
