I personally would find great excitement even if they did nothing between 17 and 18 other than just go through and touch up the theming of the park as a whole. I'm going to be that old guy now that throws a hissy about the old days, but honestly, that's what I'm looking for. I've noticed since I had kids that when I take them places I remember getting such joy from as a child, that I want them to feel the same joy I felt as a child walking in. I often have trouble separating myself from them when it comes to this. When I walked under the international restaurant and into the expanse that is international street the other day, I felt a little bit of it, but not all of it. I miss that musical build. Quiet orchestral fanfare music as you walk up to the gates, followed by louder versions playing as you walk into the park. I miss walking through the park and physically feeling the feel of each different world. That feeling like you're passing between different places was awesome. It would be cool to feel that again, but I know Cedar Fairs isn't very big on theming, so I will not expect that.
Then I also realize, my kids don't care or notice, they want to ride the rides. They have been asking me all week when we are going back. Disney World at the beginning of September is the next stop, but I have every intention of trying to get at least 1 or 2 more KI trips in this year, preferably better planned, since it was just my wife, the 2 kiddos, and me, and I didn't get all of my coasters in!!
