where do you rent most often? in nyc area they dont seem to give much respect to platinum and prob wont get better upgrades then luxury. the T&C say thats all you get. so benefit over pc would basically be pickup/drop off from terminal (maybe even from house, i think thats what the csr said to me on the phone) and 4hour grace
You're right for most locations. The Hertz at 20 Morris in lower Manhattan has woman who is very professional and courteous, whereas the 13th St. location is a disaster.
PC also has a guaranteed upgrade, only difference being that PC is limited to Full, and plat SEEMS to always get you an upgrade.
I also just found an great cdp to get a 4 hour grace period no matter what status!! It's CDP#211762 - officially exclusivly with amex plat, but ppl have been successful without the card as well.
