From our cruise, the one recommedation i have is to book the volcano tour with Big Island Volcano Tours and Excursions Hawaii
. This is a tour that the ship couldn't help us with. Princess has the volcano and nut farm for $150 and there was also a waterfalls tour for around the same price. We decided to book privately and did the volcano, nut farm and waterfalls for $70. We were met at the cruise ship terminal by our tour guide who was waiting for us as we got off of the ship, and our van was waiting for us at the curb. The van was new, clean and there were 8 of total on the tour. I am really happy wefound this tour and if you are on Princess, i really recommend looking at this tour before you make reservation. The price is great and so was the tour.
