Start by researching attractions online. You can get the hours, admission prices, and a good look at the venue before going. We found the Atlanta CityPass at www.citypass.com. For a flat fee that was about half the price of buying tickets separately, you gain access to many major sights. Also, the pass helps you circumvent lines. Simply sign up and pay online, and then pick up the pass at your first stop.
Visit www.mapquest.com or another Internet mapping service to plan routes using as many surface streets as possible to avoid busy interstates.
