We will be in Kona for Christmas with our 18 month old. We are debating whether to take a stroller or our nice carrying backpack. We have never been to Kona, so I don't know the terrain or types of things to do with a toddler. If we do a bunch of off-road hiking or something, the backpack makes sense....but is a stroller more practical for shopping in town and other activities? Anyone travelled there with a toddler and can provide any advice?
