Tour was a perfect way to get a great overview of Oahu when you're short on days. Tour guide, Rebecca, made the tour. She was so knowledgable, interesting, funny, and upbeat. The tour itself was a great day, but she made it an incredible experience. One word of caution however ..... Viator's description makes it seems as though you will see Diamond head. In reality the only way up is to hike the steps. What you see is a glimpse when you drive by on the main road.
This tour included too much riding around time and not enough time at the various stops that were included. We would ride for 45-60 minutes, then get to spend maybe 20-30 minutes at a pre-determined stop and/or for a couple of photo ops. There are no guided tours arranged at the various stops where something like this would seem appropriate, rather, you were left on your own to wander around and do whatever you wanted. We had Rebecca as a tour guide and she was a very nice young lady but needs to better learn how to interact with her charges to make a full day tour more interesting. Only take this tour if you enjoy spending 6-8 hours on a tour with most of it being on a bus.
A wonderful day, with a terrific driver/guide. Very relaxing and lovely to see the entirety of this beautiful island.
