The problem is that traveling is very challenging right now. It's a lousy situation. Paying for a year of school is a lousy option right now, a typical gap year with travel/activities is tough, and employment options are very limited. I guess if I were an incoming senior, I'd do my best to wrap things up and get a diploma this year--one school I know is basically letting only seniors among undergrads back on campus in the fall with the message to wrap up whatever they need to do in-person to graduate and plan to be online in the spring. For anyone else, if I were in a position to deal with it financially, I'd take a year off and spend it as usefully/enjoyably as I could.
