What do you want to know. About the ship or about the islands.
We are going on the Radiance in may to Hawaii and I´m planning our tours. We make a Circle Island Tour on Oahu, without Pearl Harbor and Arizona Memorial, costs a lot of time.
If your time is not too limited as ours , than take the Hana Highway Tour on Maui.Or if you are interested in whalewatching, this is the best time to see humpbackwhales with their babies. We have done that on a wonderful sailboat, but got the sunburn of our life.
For Kauai I would recommend a helicopter flight, something you will never forget, seeing the beautiful waterfalls, the Waimea Canyon, the Napali Coast and more.
On Big Island of corse the Volcano Tour.
We have been there in 1999 and counting the days until we will be there again.
Enjoy these wonderful islands.
