Unfortunately for the students at Ave Maria, there is virtually no nightlife on campus. There are parties from time to time, but they aren't enough to justify any kind of nightlife on campus. Naples is approximately 30 minutes from campus and offers pubs and other places to go out at night. For underage students, it's more or less the same situation. Although entertainment can be found on campus, many students find it to be insufficient.
Of course, students can still find things to do on or near campus, such as hanging out with friends in the student lounge, going out to eat at The Pub or The Bean, or getting involved in a bunch of clubs and intramural sports. However, if the goal is to get off campus, be warned that you'll be driving no less than 30 minutes, possibly more, depending on your final destination. So, if you're looking for nightlife at Ave Maria, be prepared to fill up on gas or find something else to do on the weekends besides hitting the city because Ave Maria isn't exactly the place for nightlife.
