Taxis, door-to-door transfers, car rentals, and car sharing are also available, with taxis being the fastest but pricier.

The most practical way to reach it from downtown is by car or ride-share via I-290/IL-64, which takes roughly 45–60 minutes in normal traffic, or by taxi for a similar cost but less flexibility. Public transit is limited to a combination of Metra commuter rail to West Chicago or Wheaton followed by a short taxi or ride-share, which is cheaper but slower and less convenient.
