I actually LOVE the "Copenhagen" font. Really cool! I can see your idea with the flag. Unfortunately, I think that the Danish flag is a bit "cheasy". It would look great with the American flag - no doubt! :)
The round thing, with the flag in it - not loving it either. But I find the use of persons (since it's a very social event) ingenious!!
So, maybe you could keep the Copenhagen font, change the round thing with the flag, but keep the idea with people in the logo? :)
Thanks a lot for your time!
