I spent a week driving around Iceland in June, and to anyone, I say go. It is better than you imagine. Only two weeks before, we stayed at the Grand Canyon in Arizona, and I often thought in Iceland that it was like driving through the Gand Canyon as opposed to just viewing it from the rim. We expected it to be good, but so often we were just blown away with the almost unreality of the landscape. Oh, and 24 hour sun was an interesting experience!
