After waiting in front of our hotel for 2 hours, the driver failed to pick us up. No call or texts. After calling/texting/emailing the main office multiple times with no answer, we finally got through to someone who said a manager would call us back. A manager did call back after awhile, apologized profusely, and set us up with a tour the next day. The tour with Kristi was great; she was an excellent driver with much experience and insight into Maui's diverse history and biodiversity, and she was a wonderful guide. No negative comments on the actual tour, just disappointed to have wasted an entire day of our vacation.
