It shouldn't be *too* unbearable. Expect 30-180 minute waits for X-Flight, about 10-40 minute waits for BKF, The Villain, S:UE, and some of the other coasters.
The weather has a big effect on the attendance, also. If it is very warm, most guests will flock to the water park and the ride side may seem a little less crowded.
If the lines become too long, buy a Fast Lane ticket for $10. :)
Either way, enjoy the park and don't forget to check out the wildlife side!
