I have a Hertz weekly rental rate and now I'm returning it on Saturday afternoon instead of Sunday as originally planned. Based on some reading online, I'm concerned that the early return will reprice into a daily rental rate since I don't have Sat night stay. I booked through standard Amex Plat CDP with no other discount codes with special terms. I've read all the online rental rate terms I read don't say much of anything about minimum rental periods. On counter point, Avis states this very clearly during booking (e.g. minimum rental length and maximum length) for your current rate. I also searched the forum here, but didn't find anything - any info on this?
