I have done a lot of reading this Sixt forum, and a lot of you guys are seeming to have issues with double charges, and false damage claims. I have not had either of those issues with Hertz or National before. Should I just stick with Hertz/National? I have Plat status with Sixt from a status match but have never rented with them. Will be getting vehicles for 10 days in Hawaii this month. Thanks!
