Having transportation to get around the campus is normally unnecessary. The distance between each building is very close and many people can get around by walking. The only time you need transportation is when you’re thinking about leaving campus. Once you leave campus, it's all large highways and big roads, so it's best to have your own car, but a bus may be a good second option.
Unlike a lot of other colleges that are located in a city and have access to public transportation, Maryville is located in West St. Louis around a suburban area, so bus routes are limited. Metro buses do come every so often, but the only bus stop at Maryville is outside the school. Check the routes for any new time changes that may occur. If you have the patience to wait for hours, then the bus could be for you. It still will get you around to your destination but the buses come every couple of hours, try planning accordantly.
Maryville also offers a shuttle service two weekends a month that takes students to Boone’s Crossing so they can pick up any supplies they need. It may be a good choice if you need to get everything in one trip without the hassle of waiting for others to take you.
