My husband and I are planning to visit the Big Island for a week in May. We were thinking of splitting our stay with 2 nights in the Volcano area and 5 nights at the Mauna Lani. We should be able to fly into Hilo and out of KOA. Is this a good idea? We'd like to spend a full day exploring the park and thought staying in that area for part of the trip may save us some time. Thanks so much for your advice!
