Our family of four, including 2 adult children, are planning a 2 week trip to Hawaii in May. We intend to spend 4 nights on Hawaii as our son really wants to explore Volcano National Park. We had thought about trying to split our time on Hawaii into 2 days near the Volcano and 2 days on the west coast of the island but after doing some research, I think we need to just stay somewhere on the west coast for all 4 days. Is this the correct thinking? And if so, where should we stay that would be close to the ocean and the Volcano?
