We are a couple in our 30's; we used tour.is (www.tour.is) to organize a 9 day trip around the ring road in late May/early June; Ingi was our contact. We decided to visit Iceland at the last minute and Ingi litterally planned it with only two weeks notice. He was always very prompt when replying to all of my e-mails, which I really appreciated. The prices were competitive & there was a great selection of self-drive itineraries.
The itinerary was well-organized, the hotels (a mix of hotels and farm holidays guest houses) were great and the suggestions for activities and sights were perfect. Numerous road maps were provided, including a big road atlas and a large map with our personal route highlighted and the location of our hotels circled. We needed an automatic transmission car and while other companies said that might not be possible, Ingi was able to find one.
I have to admit that I did not do a whole lot of research into tour companies since we had such a last minute trip, but we really lucked out with tour.is. In summary, we had a wonderful time & would use tour.is again without hesitation.
