i was trying to make a res for next weekend in san diego, and when, as normal, i entered my fastlane number, it came back $5 higher per day than without. so i made it without and called to put the fastlane in the res. i think the car rental business is right behind the hotel business, which is right behind the airline business, in terms of weirdness. one more angle to check on next time. as though there weren't already enough.
