My wife and I travelled with some friends to celebrate a milestone birthday, however it was also a destination on our bucket list too.
We found Waikiki extremely expensive and catering to tourists. It was very nice toget out of the rat race and visit turtle bay and snorkel with turtles. Pearl Horbour Is also worth a look, but don't spend a lot of money on a tour.
The ship was very under staffed in the 'free' restaurants, which meant you could not get a table for up to an hour even though tables were empty. This was frustrating.
The cabin was quite reasonable, however for the price you can get a lot more on other cruise ships. Not shore if I wrote the correct category, however it was room number 10030.
Hired a car and went up the volcano. Very misty and wet and hard to see the crater. If you want to see the sun rise you must book three days in advance. Drove Hana road . Very scenic. Very limited shops but nice to drive around.
