We got into Oslo a bit later than we had hoped for after a delayed flight, but the process upon landing was pretty simple. We found the Flytoget Express Train and took it to the Nationalthetret station. All we had to do was swipe our credit card at the turnstyle. We didn’t even get a ticket.
The train was quite full, so we sat on our luggage until we arrived 20 or 30 minutes later, I think after about three stops. We walked a few short blocks along the side of the park to our hotel, Hotel Christiania Theater that was in an absolutely perfect location. I really scored on this place, especially given the price. The only downfall was that there wasn’t any A/C, and it was unseasonably hot in Norway, but I suppose a lot of hotels don’t have A/C in the nordic country.
