Flying into GOT Landvetter around 10pm tomorrow night with another flight next day at 6pm.

Should I stay at one of the airport hotels, such as the Scandic, or is it easy enough to get a bus or whatever into the city at 10-11pm?
Not sure whether to get a hotel in the city so that I can sightsee a bit earlier in the morning (only got a small and light backpack, so no luggage).
