King's Island (a Cedar Fair amusement park just North of Cincinnati, OH) is testing out a rewards program this season that tracks and rewards visits and in-park purchases. So far it seems like a promising program. However the member site, funperks.com does not give much information regarding rewards or rewards levels. Even after you register, It does not tell you very useful info such and spending or spending totals, available rewards, or what is even tracked or how to achieve the next level!! I found a couple amusement park forums that discuss the program a little, but I thought this might be a good place to compile experience and information from actual members.
Also: If you have a season pass and register for funperks, you will automatically get an unlimited soft drink voucher for a future visit as your first reward.
