EXCELLENT!!! As this tour group was new to Viator, I was a little nervous but took a chance. I'm so very glad I did. I received a confirmation call from Jill the day after I booked. Josh picked us up right on time from our hotel in Kona in the tour van. We were able to customize the trip to our liking and Josh was extremely informative. Josh was also very accommodating as one of our group was limited in their walking ability. Because of Josh's familiarity with the area, we were able to avoid the larger crowds which made the trip extremely enjoyable. Our tour was approximately 11 hours and we were able to see everything on the group wish list. Josh provided umbrellas and ponchos as needed along with a water and snacks. We were able to adjust stops to take photos and breaks. I would, without hesitation, recommend the local tour company to anyone that wishes to view the wonders of the Big Island. I will definitely use them on my next Kona trip. Thank you Jill and Josh for the professional services, friendly and informative trip and the perfect means to view the many beautiful sites of Hawaii. Mahalo!
