We were originally planning on 12 nights, but are now thinking we will add a couple of nights, in total, to our trip to Hawaii. We will spend 14 nights, to be divided between the Big Island and Maui. We've been to Maui, once, 7 years ago, but only for 5 days. We've never been to the Big Island. What would be the best way to divide our nights...7 and 7? Do I need more time on the BI because it is so large?
