Thanks Pinnipped, I rented a lot of car in US, with AVIS, Alamo, Dollar.....in the mainland and also in Hawaii and every time the rental company gave me the insurance coverage. Now, the problem, it's thai in Lanai Island, 808hummers and dollar, don't give an insurance coverage, the required that the people that rent a car has the persolan coverage, and that's impossible for a foreign people like me.
If i'll find some company that provide me for 25$ a day the insurance i'll very happy, the problem it's that i can not find with 808hummers or with dollars this possibililty
