Worked for me, too. I used to have Hertz Gold with the Amex Platinum but when I switched to Delta Amex Platinum, it did not renew. So I am glad to have this opportunity. Two rentals coming up in the next few weeks.
For work trips, my company rents direct billed Avis cars, so I don't get to use my Wizard number.
I use Hertz for personal travel.
