I,m sorry but easy fairly inexpensive transit between an airport and a downtown DOES make a difference to both conventioneers and other visitors. I'm going to Chicago in two weeks and will take a shared van service from Midway to the Loop for only $54 roundtrip for two including luggage! We're coming to Detroit next weekend for a visit and have to rent a car and pay $20/day at the Courtyard on Jefferson for parking. And no the local busline is not an option.
