I have been keeping an eye on this, being an alum and knowing how greedy they are when the see a cash cow so take a look at the transportation website for details. Its gonna happen after winter break is over or when they "deem it a special event"
"Through the end of the fall semester, visitors will be required to pay for parking only on weekdays between 7:30 a.m. and midnight, and during any special events as determined by the Parking Office. Following the University’s winter break, the East, HUB, and Nittany decks will move to 24/7 operations, with a valid permit or payment of the applicable parking fee required 24 hours a day, seven days a week."
