I noticed you planned to take a na pali boat or helicopter tour in Kauai. Let me recommend a perfect Kauai activity. We took an air tour with Air Ventures and it was incredible! The one-hour tour is in a luxury plane and you get to see the entire island. They offer free transportation for cruise ship passengers and have a perfect safety record!
Donna and Joel made our tour so memorable. Every one on the flight got a window seat and we took the best photos out of the whole trip on that flight. For only spending a day on the Garden Island we felt like we had discovered the whole island!

Have a great cruise!
