NCL tours are short and almost twice the price of tours offered at the dock or online. Smart seasoned travelers will rent car from Thrifty (in advance) and drive the tours themselves; spend much more time at their tour destination, see more interesting places.
We did the Hawaii cruise twice in consecutive weeks; the first week we spent $2,000 on NCL tours and felt cheated, the second week we rented a car (never had the flat tire NCL promised) and saw the Islands up close. The second week we shopped in the stores along our route that looked interesting and not just the ones with a NCL kickback. Big savings!
I had a blackberry with Google Maps, saved the location of the ship, destinations and car rental in the favorites and never had problem navigating. Thank you Google!!!
Unfortunately, NCL is the only cruise line that offers a Hawaii only cruise.
One other hint, get a starboard cabin if you want to view the islands from the ship. Port side cabins only see the sea except while docked and NCL only docks at industrial locations.
