I live in Sweden, and it sucks to be honest. The clubs here are nothing but binge drinking and crappy music, at least what I've found. Also, people are not nearly as fun as they should be. The main problem being everyone's more focused on getting drunk than having fun and dancing. This is probably not unique for Sweden in any way but it's the sad truth.
I've been to Madrid, Rome, London and Paris already. Seen most of the stuff to be seen there and though enjoyable, this is not a tourist trip, more for the partying and relaxing.
Also, I'm not a totally into-it stoner, but I enjoy it and from what I've heard Amsterdam is a good club landscape -- and so the coffee shops would just be a plus. But then again London seem to have many good clubs too, like Ministry of Sound (don't bash me if this is a total douche-club or something, I've just heard it's a great place for club music).
Anyway, a lot of nice ideas and opinions, thanks a lot. Keep them coming.
