We usually use Alamo, but my goodness - they wanted 470 for a compact for our dates. Dollar wanted 208 for midsize or better. We reserved with Dollar. Any unexpected surprises? We have NEVER rented anything but Alamo.
For all I know, another company will be featured next month.
I might have used Dollar before at Orlando but I don't remember. But I do remember my worst car rental experience, which was with Dollar (another city). A two hour wait in line to get a car, and when I finally got up to bat, they were pretty much out of cars except for one they could let me have for one day and I would have to bring it back and exchange it.
