As for actual advice, KK is kind of set up to do whatever at you leisure. I spend time wondering around and riding whatever I felt like and still got a lot done including hitting the 4 main coasters multiple times (sans T3, not that great a coaster IMO). Just try not to traverse the bridge too much. Lots of climbing involved, though, there is a crosswalk below it. Also be forewarned- the water park side of the park makes no sense from a logical path point of view.
