Based off my Marriott status I was placed on the fast track to Five Star with Hertz. This is per Marriott/Hertz partnership agreement. Said it would take 5 days but received email in 3 days.
Per email:
As a Marriott Bonvoy® Platinum Elite member, rent seven times in the next 12 months to be upgraded to Hertz Five Star® status.
