Six Flags Great America (SFGAm) Discussion Thread in Theme Parks, Roller Coasters, & Donkeys! Posted February 18, 2017 If you know you are coming to Great America, make sure you post on here in the couple weeks beforehand. Some of us are very close to O'hare/NW side, and several of us locals on here will be at the park any given day. Good way to make good contacts, too! I've met some nice people on through this forum (and other forums) in the past. A couple people I'd rather forget as well... I love my car... I'm also open to public transit, but I can't imagine taking it all the way to Great America. If people are flying to O'hare I may be willing to meet up for a trip to the park. Same goes for people near O'hare and the NW side. I had a good experience taking the PACE bus to the park. I got on the first bus of the day so there were only a few people on it. I think I got on the last bus to leave the park and it was about three quarters full. The fare was cheap and it didn't take much longer than driving. Also the bus was really clean and that's probably because it's a suburban bus. I would say this is the best option for out of towners. Do whatever you feel comfortable with and fits in your budget.
