The best airport to use is O'Hare International Airport; it is much closer to the learning center than Midway Airport.  Another option is General Mitchell International Airport in Milwaukee.  Click on the links below to visit each airport's website:

If you have arranged for R & B at the learning center and do not want to to rent a car, you may take a taxi directly to the learning center.  We recommend that you utilize American Taxi, as rates to Wonder Lake can be outrageous unless arranged well in advance of your arrival.  In advance of each course or session, we will e-mail a list of other R & B attendees to you, so that you can contact each other to arrange ride-sharing.  If you prefer to travel alone, when you arrive at the airport, go to the phones in the baggage claim area and call American Taxi at 1-800-244-1177.  They'll have a taxi there within 10-15 minutes, at a fair, standardized price, and they accept credit cards.  You can visit American Taxi's website to view rates and policies by clicking here.
