Looking at going to Hawaii this summer but am a little overwhelmed at the options as far as what islands to visit, where to stay and stay what to do. We’d love to some light hiking trails and see some nature, lay on a beach a few days, and take in the culture. Would like to visit for about 10 days, what type of budget would be needed assuming we stayed in midrange hotels and only ate out for dinner and small snacks? And what is the easiest way to schedule flights between islands, car rentals, etc? Worth just getting a travel agency to plan all that for you?
