Booked my rental online...ONLY TO FIND OUT THE CAR
Pros: Nothing. I didn't get a vehicle.
Cons: The fact that my booking was confirmed, yet when I went to the counter, was informed that the website was making bookings for cars that didn't exist. They had absolutely zero available vehicles, yet I was "confirmed" by Alamo/Kayak. Would have wound up stranded in Grand Junction, had it not been for another gentleman who actually did get a vehicle who gave me a ride back to Denver.
