Non-stop flights are available from St. Louis, Chicago O'Hare, Cincinnati, and Detroit.
More competitive air fares are usually available into and out of Chicago O'Hare
airport and Champaign-Urbana is typically less than a 3 hour drive.
If flying directly into CMI,
the major car rental companies have outlets at CMI.
For those wishing to drive, Champaign-Urbana is at the junction of three major
interstate highways: I-74, I-57 (to Chicago) and I-72. Chicago, St.Louis, and
Indianapolis are all less than a three hour drive down one of the three
mentioned interstate highways.
And for anyone worried about it, while it is possible there could be
some chilly weather, it is also quite possible that the weather will be
"balmy" and "spring like", so bring appropriate clothing for either
eventuality.
