Honestly, in order to keep prices reasonable and compete with other parks across the country, sometimes there are things that just have to be cut. And sometimes theming on less popular rides (Disaster Transport is a great example) is one of the things that can be lessened. Seriously, why waste the money on theming on a ride that is no longer a main attraction??
CP goes more for the quality of the ride and the upkeep of the ride itself... to keep it in working order and safe! One things I did notice are that the rides at CP look better kept and the paint jobs are more up to date... don't see quite as much rusting as you do at KI...
Also, at KI it seems as if the ride ops aren't quite as well behaved. However, I must admit that it is nice to be able to say something to an employee of KI and have them speak your language.
Plus, are you actually going to the AMUSEMENT parks for the landscaping?? In my opinon, I'd much rather experience an amazing ride on a top quality roller coaster than pay that much attention to the landscaping... KI is a beautiful park, I must admit... however, it goes back to the paint jobs on the coasters... poor poor poor upkeep and certain coasters look very rusted out.
I guess if you want a park that is really big into themes, go to DISNEY, because that is not the main focus of CF parks... its more about the rides itself.
