I won a contest through the Stills to go, but only for two nights, and we only got to go to the last night of the festival, which was a 4 day thing. It was an incredible experience though, and Reykjavik is a lovely city, so if I ever have the means, I plan on going back. Most everyone in Iceland speaks English well, are very friendly to tourists, and there is spectacular scenery to be seen during the day if you get out into the interior.
