Yep, that's pretty much what every tourist here does! But it's really nice, so it's worth it ;)
If you come to Norway, then don't expect to get drunk too often! You would not believe how crazy expensive drinking alcohol is here. Regular bars does charge you $11-15 per 0.5L of beer!
I already heard that. It's okay, even though I'm Irish I do manage to survive without getting a regular skinful!
