Dunstan was a very friendly and responsive co-ordinator. He assisted us in achieving our desire for a non- traditional route. Some communications issues arose in the transfer from Dunstan to the guide who actually took us into the park. A reminder to ensure that close and detailed communication is maintained. Tipping can be a source of tension at the end of the trek, especially if conflicting expectations arise All in all though we had a great trip and our thanks go to Dunstan
