Hi I will be visiting Urbana-Champaign this weekend for a campus visit and I am flying into the campus airport (recommended by the department/they are paying for it) but if I end up at Illinois this is certainly not my plan for how to get there in the future. I know that there is an Illini bus system that goes back and forth from campus to Chicago for about $20 - $40ish (http://www.illinishuttle.com/). In terms of Chicago I think I would prefer the bus/train system as compared to driving but that might just be my own preference.
@badgerslp, I will also be in a hotel this weekend and I am in need of places to walk to as well so if anyone knows please let us know!
