As part of a bachelorette party, we had a private tour with Loki the tour guide. I cannot say enough good things about our experience, and I am talking on behalf of all of the girls. Not only did Loki specify the tour to what we wanted to know, but he was completely accommodating as the rain delayed our progress a few times (he even extended the tour just so we could finish and see some specific sights that we were interested in). The stories Loki told were so engaging and he was very knowledgeable on the subjects at hand. Likewise, he was incredibly nice and patient! (as we were all a little tipsy!) Truly, a great experience that I would highly recommend.
