Taking a cruise from Oslo? Where can you go?

I am thinking about going to cruise this summer. I am thinking about one option. So I must ask you for advice. What if you are taking a cruise form Oslo? Where can you go? Has anybody has experience with this? Any guidance is more than welcomed. Please share your experiences about this topic with me.Thank you in advance.

I have never been o cruise from Oslo. Is that thing possible. I have been in Oslo couple times. I had a really good time there. My old friends live there, so every year, I go to visit them, and spend there one week. I think that Oslo is very beautiful city. I suggest everybody that I know, to go and spend some time there. But now, you gave me a really good idea. I could go next year on a cruise. I can suggest that to my friends that there live, also. They must know something about that cruising. I will ask them what they know about that thing? It never crossed my mind to suggest theme thing like that. Thank you for very nice idea.
