I don't think I'd go to Schaumburg if we go.
I don't see the point for me, if I go there it's a big hassle to get out there, and afterwards not many bars in the area to go out afterwards.
Plus Schaumburg != fun area. Schaumburg is ok w/ Woodfield and all, but it's not exactly a fun area. Gold Coast, Lincoln Park, Lakeview is a lot more fun and cooler. PLus if the D&B sucks more options exist in Chicago.
Ok, directions from West Lafayette, IN to the Chicago D&B.
Take I-65 to I-90/94. When in Chicago, get off at Monroe for simplicity. Go east on Monroe for .75 miles until you hit Clark. Go North on Clark for 1.5 miles until you hit 1030 N. Clark.
