Six Flags Great America (SFGAm) Discussion Thread in Theme Parks, Roller Coasters, & Donkeys! Posted August 6, 2014 Regarding on how crowded the park gets, it is really difficult to say. Last Tuesday I was there and it was busy. We ended up with a gold qbot and our wait times were 30 mins, much less than waiting in line still so we were grateful for that. The wait for Goliath alone was about 120 mins, and it looked like the other coasters were about an hour (or more) wait. I went to the park yesterday to meet up with some friends after work, and we waited only a matter of minutes for Whizzer, and decided to do the single rider line for Goliath which was about an hour. The posted wait time for Goliath yesterday was only 90 mins, but it could have been less. I think as you get closer to school starting you'll find that the crowds will be less, but that's just my opinion.
