I'm going to be on the big island for about 3 weeks starting the first or second week in february. Does anyone have any tips on renting a midsize car. I looked around at some of the rental company sites and I saw some quotes of $600 per week. Wow! The lowest I saw was at Hotwire.com for about $326 per week but that still is more than I have paid in the past. And I like to have both my wife and I drive. I'm a member at National and Enterprise so both of can drive if we rent through them at no extra cost but their rates are so high. Any advice?
