I have rented cars from Enterprise for many years. DON’T ever modify your reservation! If you do, you’ll end up paying more just like you made a new reservation. My plane was a late night flight that was delayed 1 1/2 hrs so I modified my arrival time through their app to make sure I’d still have my car. It only cost me $100 to do that. But I didn’t find that out until I showed up to pick up my car. Even showing them my original rental confirmation didn’t change their mind. I was told it would be corrected by 5 different customer representatives on the phone but to no avail. I’ve spent thousands with them over the years but they are losing my business by saying they would correct the problem and then were unwilling to do so later.
