Too Many Airport Choices
I'm from Chicago. DON'T fly in to Midway. Midway is on the south side of the city and you have to drive through Chicago to get up to Wisconsin. Traffic on a Friday in Chicago is horrendous. At least with OHare, you are north of the city and the drive will be more quick. The average time WITH NO TRAFFIC to get to Lake Geneva from OHare is 90 minutes, but for a Friday, who knows. Milwaukee airport is easier, smaller, closer, little traffic and a much less stressful drive. Only downfall to Milwaukee airport is less flight options and possibly more expensive. With all this said, I vote Milwaukee for visitors.
