Sam:
Follow I-65 south out of Chicago to Indy. Pick-up 465 on the north side of Indy and follow it south around the west side of the city. Then get onto I-70 West and take it to Rt. 231. Go north on 231, then right (east) on US 40, and right again on County Rd. 550E.
If going to the Walden Inn, go back to 231 and follow it into Greencastle, then make a left on Seminary Square.
Drive time from Libertyville should be no more than 4.5 hrs.
