Most students find the prom a lot more fun if they go in a group.
Couples can share a car, and several cars can go together and arrive at the dance at the same time. This way you can sit together at the same table and enjoy each other's company all evening. Remember that the earlier you arrive, the better your chances will be of finding an empty table where you can all sit. This gives everyone an opportunity to get a good start on the evening. It will also give some parents a chance to make a fuss over all of you.
