If you have an iPHONE, there is an app called "Ride Hopper." You can get it, select which park you want, and then it shows the wait times for each ride. It is updated by people who are at the park on that day. Its a great app, you should check it out if you have an iphone.
20 minutes to 2 hours depending on the ride and what day you go. if you go on a week day the wait will be less time.
The smaller rollercoasters had a 10-20 minute wait, the bigger ones had a 20 minute-1 hour wait.
Most other waits were 30 min or less. Gemini & Magnum, we got on right away, only waited for a train or two. We went in the beginning of June though. July & August will probably be busier.
Those waits are probably when park is real busy. We went on a Thurs & Fri. Longest wait was approx 45 min for Millenium & almost an hr for Maverick. Evening was best time to ride. Got on Dragster 2x each night w/in half to 45 min time. Also after 7pm we got on Millenium 2x w/in an hrs worth of time.
