We scheduled this trip as our last hoorah before heading back to the mainland. It was scheduled for Saturday, 5/31 in the AM. We received a call on Friday, 5/30 at around 4:50pm from Lisa who said the boat experienced problems that day and would be down for maintenance. She was very apologetic and wanted to reschedule us for Sunday. Unforunately, though, we were flying back Sunday mid-day and would not have time for the snorkel tour. Lisa gave us a few recommendations for other companies in the area to see if they had availability. My husband and I spent the next hour calling every single other company on the island (the two Lisa recommended were full but then that company recommended a few others and so on), and there was not a single opening for Saturday at all (we even checked for Na Pali coast tours, too)! Unbelievable! We were so disappointed as this was supposed to be our final farewell to the island and we are avid snorkelers. Thankfully we had snorkel gear the whole week and were able to see some sea turtles and amazing tropical fish on the north shore at Tunnels.. but we were really looking forward to this excursion. I feel bad giving such a bad review when we didn't even get to experience the tour, but I felt it necessary given the detriment to our trip that it caused.
