Could be anything. I reserved a Minivan back in December for our trip last week. When I got there (Disney's Car Care Center) they were totally over sold. I ended up with a Chevy Impala. There were a lot of very upset people. They were trying to give people that had larger cars reserved two compact cars for the same price. This was a problem for most of the people there as they were by themselves and could only drive one car. What a mess.
This is the second time I rented from
Alamo and both times I had problems. The only reason I booked with them was because they were a few dollars cheaper than National. Next time, I'll pay the extra few bucks. Never had a problem with National.
