Here is a great plan (practice it myself). It sorta takes ya on a tour of the park, and at the same time gets ya good rides:
1) Head to SOB (action zone, big structure in the back corner)
2) FOF (Coney Mall, just walk down the structure of the Racer)
3) Vortex (coney mall, steel coaster)
5) Beast (Rivertown, out in the woods)
6) If you get the timing right, you should end up at the Beast at or around 11 if you get there at 10. If you have some time, I would go to 7th Portal/Smash Factory in between FOF and Vortex. Eat at Wings Diner if you brought serious cash (there meals are around $10) or if you didnt, hit Skyline right across the street.
7)Reptar
(if your hot)8)Wild Thornberrys River Adventure
This is where you sorta double back on yourself. Hit all the interesting rides b/c in the afternoon the lines sorta go even, not too long but not walk ons. Just double back and hit the coasters that look interesting. If you want to ride Face/off, I would take it first before SOB. With one car, it will have the longest wait of them all.
This is my advice. Take it or leave it cause these rides are the ones with the longest lines
