Review Summary: I would not recommend the Viator tour to anyone. The service is not worth the money they charge, and it was highly unprofessional, with several delays and issues.
I would suggest going with a local tour operator instead. They often charge the same or even less, provide private tours, and can tailor the experience to your preferences. We simply asked one of our ubercab drivers and arranged a wonderful private tour the next day to visit the locations we missed.
Review details:
During the Viator tour, we experienced several problems:
1. The driver canceled several locations without consulting us, citing his lateness as the reason. Another reason was that some people from the tour had to catch their flight. However, this should not have resulted in the shortening of our trip. He didn't even bother to ask us (I don't want to speculate, but I had the feeling this might have been because we are not American; however, let's stick to the facts). We paid the full amount, so why didn't we receive the full tour?
All these issues arose because the tour started significantly late. Here are the details:
2. The pickup was significantly delayed, with the driver arriving 30-40 minutes late.
3. At one point, the driver made an unscheduled stop at his house, causing a delay of approximately 10-15 minutes (Isn't this is unprofessional?).
4. The driver took a nap for approximately 40-minute, despite our group returning on time and waiting for him to open the van's door. We were not informed in the itinerary that we would have to wait for his nap, and this seemed highly unprofessional on Viator's part.
5. The driver was meant to provide a guided tour but he was consistently talking about his family matters, leaving us struggling to recall when he actually talked about the tour.
6. Lastly, the driver didn't have the promised refreshment like soda, which was mentioned in the Viator itinerary.
Due to these delays and disruptions, we had to spend a good amount of money the next day to book another tour to visit the remaining places from the tour. This alternative tour was far superior, more professional, and it was a "Private tour" just for my family so it added more places from Hawaii on the go.
(Even the Viator driver also told us that he gives private tours with a similar charge, so basically one can get this option from most of the cabdrivers in Hawaii).
Unfortunately, the Viator app lacks chat services, unlike the customer oriented apps in 2023, and there is no complaint box in the Viator app, but they have a feedback option with a very limited character count, which was not sufficient to explain why this tour had issues.
