first we had to get used to a day not being a day. instead it is a "24 hour period". now it's not a 24 hour period, it has become "24 hours, or the portion that you tell us you are going to use, whichever comes first". geez, if you drop the car off at noon and it gets rented out again its 2 days of revenue! i guess if you are going to continue to use alamo, you'll need to make sure your pickup and drop times are the same, so at least you have the option of returning it early. of course that'll be a charge later as well....
personally, i haven't used Alamo in years, after they forced me to take the CDW at philly or wouldn't rent. i got the money refunded, but as a matter of principle stopped using them.
