Hey guys,

I have a UK Platinum Amex and have booked a rental car (Hertz) through Amex Travel's online portal. The rental location is in Italy.

How does the additional driver cover work? Do I need to tell Hertz anything? or do I need to tell Amex anything? I will be driving with my partner (not married) and some of her family.

Can they all drive or just one of them?

I am a bit confused

thanks!
