Anytime you are looking to arrive on campus early, you have to consult with the Office of Student Life and get their permission. Exceptions have been made, but they are made on a case by case basis. If you have a good reason to be here a day early, I would guess it won’t be a problem.
FWT begins on January 2nd, so yes. Winter break and then straight to your job, and we all come back to campus by the end of February.
