Connecting with people and forming a sense of community is probably the most important immaterial thing you can do anywhere and especially Hawaii. I mention the importance of connecting with people living in Hawaii in my 10 steps to a job in Hawaii article and also in a YouTube video on how to connect with people in Hawaii.
We highlighted 4 communities that have strong local cultural ties and are really fun as well. Some of them, you can connect with while on vacation and well worth looking into.
