I have a friend getting married near Oslo at the end of September. Flights are cheap, about £70 each return. I'm just wondering if its worth taking a few extra days and touring around a little. I worry that late September/early October is a bad time weather wise, too late for the summer but too early for the snow. I'm happy to use Airbnb to keep costs down as I've also read that Norway is a very expensive country to visit. Anybody have advice or recommendations?
