We are planning our first trip to Hawaii this May from the Midwest. We hope to visit Oahu and the Big Island. Can anyone help us with info on airfare, rental cars (do we really need one?), lodging, don't miss attractions, etc, that are moderately priced? This will probably be a once in a lifetime trip for us, but we don't have a lot of money.
Any help you can give will be greatly appreciated. Thanks!
