Questions about Hertz "Ultimate Choice" pick-up at Las Vegas car rental center.

I have Pres Circle status with Hertz. I have reserved a 2-week Q4 (SUV) for pick-up at LAS this Saturday afternoon (via AutoSlash of course). I could rebook as a C class for much less $ (although I consider my current price to be good). My assumption is that I can pick any car from the PC area regardless of which class (C or above) I book, and there won't be a preassigned Q4 waiting for me. I haven't rented at LAS in a while, so I don't know what kind of selection to expect. Last January in Maui, the lot was practically empty (mostly pickup trucks), and if I had booked a C class, that's probably all I could have gotten (They had to find a car for me, and as recall it wasn't even as high a class as I had booked.)

What has the LAS rental center Ultimate Choice experience been recently, and is my assumption incorrect? Thanks! (I recognize this is not an AS-specific question, but respect the opinions of the FTers that frequent this thread.)
