If I hire a car "on the hoof" so to speak will the insurance cover afforded by my amex plat be sufficient to cover me or will I get a load of hassle from the rental agent about taking additional insurance options? I usually pre-book my car hire from the UK with a plat package from the renter (as it's usually cheaper given the free tank of fuel and extra driver) and all my my other car hire is pre- booked for my forthcoming trip, but I've booked nothing in Oahu as yet and plan to do his when we arrive in Waikiki.
I know lots of people here have the plat, can anyone shed some light please?
Thanks
