You’d be surprised sometimes.....

But in that case, either reserve would be good. Pending on if you care more about bidding power (MKE) to get days off that you need, or shorter drive (ORD). But I’ll definitely take a line in MKE then holding off to get a line in ORD.

And it’s a 10 min walk or 3 min shuttle ride from the lot to the terminal in MKE.
