We have rented a car at GLA (Glasgow Airort) for two weeks: Hertz via AutoEurope had an excellent deal for 14 days ($826 including zero-deductible SuperCover). Prepaid through AutoEurope, where the terms say that unused days/early returns will not be refunded. I assume this applies when the actual rental (say 12 days) would have been less expensive than the prepaid rental (14 days), and the renter wants money back for the "unused days."
We have the opposite problem: we actually only want the car for 12 days (but the 12 day rental + insurance rate was $1133).
If we return the car which we have rented for 14 days early (keeping it only 12 days) will Hertz/AutoEurope try to revert to the 12 day rate (charge us an extra $307 or whatever the prevailing rate is that day), or will they simply take the keys, thank us, and not bill us any additional?
