Peter was our tour guide ... fantastic! We had a small group, and Peter was interesting and entertaining, and very informative. We visited all the sights (what was possible in winter, anyway), sung along to the songs in the car and took heaps of photos. Would definitely recommend this!
It was a little unclear of who/which company we were supposed to be meeting/looking out for. Eventually found a lady who we think was our guide, but she did not accept the smart phone option of having your certificate, so this was confusing. The tour itself was great, if this was the correct person!
