Thanks for all the replies, this is very helpful.
In all honesty, I think I may have mispoke in my post. The reason we want to do Cedar Point and King's Island is to try more rollercoasters.
I don't necessarily need to ride King Da Ka and El Torro all day, but it is nice if there are rides similar to that. From the site, it looked liked both parks had good roller coasters that were different from the roller coasters at six flags NJ. So we are exicited to try the rides.
We are more rush junkies. So as long as the rides push good Gs and have good speed to them, then we are good.
