My parents (avid travelers in retirement) are currently in the air on the way to a week and a half an Kauai followed by some time in Honolulu. This is their third or fourth Hawaiian vacation and second time to Kauai. They're staying at the Marriott and since it's my dad's birthday this month we'd like to get them a helicopter tour - something they'd never buy themselves but would do. The concierge at the Marriott, by phone, recommended eith Safari, Blue Hawaiian or Sunshine. I see good reviews for Jack Harter online as well. What's the consensus here? Best value for the money and best-run outfit, especially for a couple in their sixties? For what it's worth, my dad used to be a helicopter flight medic. My mom's not afraid of heights or anything, but this is likely her first helicopter trip.
