I believe 2017 was the last time KI hosted dive in movie nights. However, they hosted the "Island Nights" glow party with ERT on select water rides in Soak City in 2018 and 2019. I believe 2020 they were going to introduce a new "Summer Nights" event in Action Zone, but Covid messed that up and that whole concept was shelved and never revisited. I also would like to see Coaster Camp Out return in some form which was held up until Covid. 

Kings Island has held "Dive In" movies at Soak City before, they just stopped either due to COVID or logistical issues. If they were to do it again I'd rather see it held in a different area of Soak City in case the fact of it being in a wave pool was one of the larger problems. I could believe that it's harder to perform wave pool lifeguard duties at night, even with somewhat adequate lighting. Maybe it could be held in one of / across all of the lounge pools or in a new large lounge pool. 

The first time I ever watched The Mummy was at Cabana Bay's pool! But Six Flags is not Universal or Disney. But all you really need is a projector and a projector screen, so it is a possibility. I've been to some small indoor water parks and even they have movies playing in the wave pool. Should KI do it? Yes. Could KI do it? Yes. Will they do it? Probably not. If they can't have all of the lights that are on the Christmas train at KI lit, how are they going to put a movie on in the wave pool? Cool idea though, I think this would be really cool!

I've really enjoyed Orion every time I've ridden it. For me, it's fine as is. While I love finding ways to re-imagine parks and rides, most of what Kings Island has to offer is good enough as is. That being said I do really want to know how feasible it would have been to put an inversion or two somewhere in Orion's layout. What would change overall? Different trains and a little more steel for the extra track/supports? The world's/North America's first inverting giga coaster might've had a nice ring to it. Now that title will be taken by Tormenta at SFOT (which is also taller than Orion), though we'll have to wait to find out how the ride experience on that coaster turns out.

I think it'd be cool if for one night they kept some of the pools open and had a movie playing for people to swim and watch. Similar to what Disney does at their resorts.
