We had an interesting issue. We had an Avis car booked for 2 days for $141. We went to the Avis counter, were handed the contract and keys, and went on our way. Later in the day, we looked at the contract and found a $210 rate. My husband spent the better part of two hours getting thru to someone at Avis. It turned out that the contract was printed at 3:15pm instead of 5:15pm when we arrived. This was a rare instance where we were actually keeping the car a full 48 hours. The two hours extra pushed it to a 3 day rental. Was it our mistake to not check the contract when handed to us? Absolutely. I suspect that a bored employee looked to see whom he had coming in and ran off the contracts. There was only one other for who he was waiting. It likely never occurred to him there would be a financial consequence.

Anyway, words to the wise: check your contract price against your reservation. While it seems we do have this sorted, it cost us 2 hours of phone time mostly on hold with Avis to do so.
