Honestly, the park would be much better off spending the money into repainting rides, training staff, landscaping, and just overall upgrading the park. Everyone as of now is just gonna show up and while they'll think the new stuff is nice, the rest of the park is so crappy they won't wanna come back until there's something new again, and with this park's track record, I think it'd be a while. This is the exact approach Worlds of Fun took in 2018, and now their park is more popular than ever, and I think M&Ds could greatly benefit from something like it
