Yeah I like the idea of a Bluey dark ride and a shoot the chutes ride.
Shoot the chutes I love because they are instagrammable. Big spray of water and then non riders can stand on the bridge and get soaked which creates a lot of funny videos. The big splash is what makes the ride iconic.
Storm coaster could have had this but because of its stupid layout one of the best features is hidden (and indeed the fact its a water coaster, to bystanders it just looks like a normal coaster with 8 person cars)
Flats I don't really care about, yeah they have less than they did previously, but IMO the park had too many so it's not super urgent.
One thing I think will make a difference is that the village parks will tend to just do about one ride per year across all the parks. Eg they'll finish New atlantis, but WnW will get nothing, and then MW will get its arkham replacement and the other parks will get nothing. (Aside from low cost things like new 3d shows or exhibits)
Whereas if DW build one ride per year for the next 3 or 4 years, that'll really build up the park and renew interest.
