A Big Mahalo to Shaka Guide Big Island Bundle!! We took 4/5 tours (ran out of time) which enhanced our tour of the Big Island beyond words. We wished we had more time, as there are so many side tours, hikes and options, that 24 hours/day isn't enough!! The app is easy to use (I'm older than a millennial), the narration is both informative and entertaining!! Some tours we did more than once, depending on our final destination. Please make all tours available in both directions, as I'm a little scattered ;) I'm so please with this app, we purchased the Kauai app full island tour too!! Thank you Shaka Guide, not only for the app and its quality, but for your quick replies to email questions!! You rock, Bra!! ;)
