I never had to worry about our rooms or traveling in an unfamiliar country because you guys took care of everything. I was particularly thankful for the map with the highlights. We used it every night when we started planning out our stops for the next day.

The suggested sights and activities were always helpful. We never would have heard of it, but after seeing "The Eggs of Merry Bay" written in on our map, we looked it up, made the stop, and it was so worth it. We were so glad to have the other suggestions, like the farm in Efstidalur, for good local food (and ice cream) when we were out sightseeing. Excellent job is all I can say. In planning my email questions were answered promptly and "with a smile" by Gudmunda Palmadottir.

What can I say, she is fantastic. It was an extremely well planned tour, the mapping was clear and distances reasonable.

And the sights unforgettable especially the troll road.
