Had a week rental here booked through Hotwire - also a "special" deal like another Yelper. Don't have high expectations and you won't be disappointed. You're basically booking for whatever car they have on the lot. I didn't feel misled at all with my booking.
No issues, except the car had the maintenance light on, so I'm not sure how on top of things Thrifty is at inspecting their cars. Staff was nice.
I found it weird, though, that you just get into your car and go, rather than passing through a tollgate before leaving the lot like every other airport rental place I've been to....
