What to expect in terms of crowds for Coatermania?

I have never been to the park before while Coastermania is going on. I'd love to take my son to the park this Friday since he will be out of school, and we can finally use our passes for the first time! He's only 6 so we'll be mostly on the Camp Snoopy rides. Will the park be super crowded? I wasn't sure what to expect, thanks so much!!

I'll let you know that day

the weather doesn't look that great for friday so the park shouldn't be too crowded.

If you're primarily sticking to the kids areas, you probably won't see many Coastermania participants. The effects on the overall crowds are small at best.
