I donh't understand why Cedar Fair doesn't have some kind of fast pass unless you are crippled or pay a horrible VIP pass. We were lucky to arrive at 6 Flags NJ (whatever its name is) about and hour and a half before it closed and rode El Toro 11 ELEVEN times and only having to change seats about 2 times. We would've gone home after that, if we didn't live in Pittsbugh!
Have used their flash passes, and definitely get the season passes with parking.
I don't get a Kennywood season pass since I am over 55, and it is amazingly cheap after 5:00. It also helps to belong to ACE, who had a wonderful ERT on K'Wood's new coaster in October before the park opened for their Fright Nights. My partner commented that they all looked like characters from the comic strip "The Far Side", but the TPR gang I am sure could be compared to some other comic strip - will let you decide.
