We are also going to Hawaii in may with the Radiance. And we booked our shore excursions with independant tours.
But for most of the tours you need more people to get a small bus or van.
Look for www.Hawaiigreentours.com
and check our special site portreviews for more information.
I know, that some people rent a car, but we like to be driven around and see all the beauty of these wonderful islands. We have been there for twee weeks in 1999 and canīt wait to see it again.
Good luck, Marita
