My husband and I have been to Oahu twice, and Maui and Kauai once, but have not yet been to the Big Island. We really want to see the Volcano National Park. On our next visit, should we book a couple of nights on the Big Island or should we do an all day tour from one of the other islands? We were thinking about a week in Kauai and another in Maui. My husband would like to see the volcano at night, and I have seen that some of the tours let you experience that. We live on the East Coast, so we treat each visit like it might be our last. Looking for the best experience, but are cost conscience.
