How much is parking here versus the Park Inn. We are arriving by flight at 6PM in OSL and leaving the next morning to drive to Bergen. Wouldn't mind pasisng through Oslo city that night we arrive or next morning.

Rental car is $90+ per day whereas it appears 3 bus/train rides into Oslo round-trip would also come to about $90. Thus its a wash - but if there is a parking fee that may sway our decision to not pick up the car until the morning.
