KI: Remove Days of Thunder (Go Carts) and put a small intense B&M Invert there, about the height of Batman clones, but have an Immelman, TD Loop, ZeroG, 2 Corkscrews, and a super intense helix. Than make one side on Racer backwards again. Give TOPGUN a paint job. Remove Invertigo and Congo (Intamin Flume) and put in a low to the ground Intamin LSM with good air, and a very twisted layout and a Norwegian loop thrown in somewhere. Not get Planet Snoopy, but instead bring back Hanna Barbera Land and Phantom Theater, and make a skyride from HBLand to Oktoberfest like back in the day.
SFKK: If possible, give Chang floorless or sitdown trains. Run Greased' Lightning good like Astroland did. Remove Twisted Twins and make an S&S Air Thrust coaster (maybe Hypersonic?) in it's place along with an S&S Combo tower. And lastly make a Superman or Batman clone in place for T2 which will be remove.
SFOG: Paint Batman yellow like Great Americas. Stop advertising on Mindbender's train, if they're going to advertise like that than atleast do it on a bad coaster... Ninja! Remove Shake Rattle & Roll and the Wii thing and put in a GCII like Terminator in that area. Put in a Gerstlauer Spinner like Pandemonium in the parking lot next to Thomas Town. Fix up Cyclone and GASM, and add some more flat rides. Lastly, get some new Vekoma train on Ninja so it won't be hell riding it.
