My fiance and I are travelling to 3 Islands of Hawaii for our honeymoon in 4 weeks time and on Maui and Kauai we would like to rent a car, however have NO idea which Insurance option to select. We are from Australia and the insurance options are so different over here. In Australia it's quite simple - third party (to cover for damage to someone else's vehicle) or Comprehensive which covers your own and others..I have had great difficulty and starting to get myself quite stressed about the insurance of vehicles in Hawaii and which option to select. We just want to ensure we are covered for any damage to our vehicle and others, in the unfortunate event something was to happen, as well as injuries to people involved etc.. and not out of pocket anything (or at worst, a less than $500 excess). Any tips on what insurance to select? I have seen options for Collision damage waiver, unisured motorist protection, supplemental liabity insurance... I am just at a loss as to which one we need that covers us! Any help would be greatly appreciated. Thank you. Also, is it necessary to get a GPS on Maui and Kauai?
