We're going to the Wisconsin Dells later this summer. I need opinions: should we take the car ferry that goes across Lake Michigan and lands in Milwaukee, then drive to the Dells from there (abt 150 miles total)? Or should we drive around the lake through Chicago (abt 360 miles)? The ferry isn't cheap--it's $70 per adult (M is free), $80 for the car, and about $44 for surcharges. Is it worth the boat costs to save 210 miles on my car, plus saving about an hour on the road? My husband says no, I'm on the fence.
