There are places for all students to hang out at night. It's definitely easier for the older students to find somewhere, but there is still something for everyone within the city. Most of the clubs are for 21-and-older only, but there are a few that cater to 18-year-olds as well. Anyone under that age might have trouble finding a club, but several malls and eateries can provide them with an equally fun experience.
Getting to clubs and bars can be an issue when a student lacks transportation. MARTA stops running early in the morning, so having a car becomes essential. Most students are fine with hanging around campus, however, so for them transportation becomes irrelevant.
The only real parties on campus are thrown by the frats or sponsored for big events by OSA. Clubs have parties from time to time, but they're usually only for members, and they usually take place off campus. On a regular night, many students just hang around the dorms talking to people, watching movies, etc. While this is still fun, it lacks the excitement of Atlanta attractions.
