With respect to the suite, if I'm not travelling alone, or am having guests over, or will be eating in the room, a suite is nice. Especially if there is a second bathroom (or 1/2 bath). More often than not though its when I'm travelling alone that I get the suite... In some hotels the suites seem to be better "tended" to in the dept of toiletries, robes, etc. I think it really does show "we appreciate your business" however, and is a no-cost item to the hotel if the room is going to go empty. There are some particular hotels where having a suite upgrade is nice because (one comes to mind) they are corner rooms on high floors with sweeping vistas in 2 directions. But really in all the years of rooms and suites I have had, and I can recall several very nice suites, only 2 stand out as truly memorable and impressive - the W (SF) and the Plaza. I could have moved in to either. I tend to agree that in a hotel with a lounge level, access to that is generally more important.

With resepct to the cars, I generally prefer a smaller car - so long as the AC works well and there's a respectable audio system in it.
