Does anyone have experience utilizing Celebrity's helicopter excursion in Kauai? Where do they depart from? What spots do they visit? We're debating between the Celebrity excursion and booking on our own at Jack Harter Helicopters, which departs from a location very close to the Naiwiliwili harbor. Got a brochure from Jack Harter last time we were in Kauai, and I like the spots they visit.
