I know Parents Weekend is more than 4 months away, but for those of you who haven't booked their hotel, do it now. As for rental cars, last year when booking a rental car out of the Denver Airport for parents weekend, rental companies were showing rates of $50.00 and $60.00 (or more) per day for standard cars, which was outrageous. I checked today for rates and found the following: Enterprise standard car (9-1-2011 to 9-6-2011) is $270.95. A standard car on hotwire can be purchased for $32.95 per day ($241.57.) Last year I got a car on hotwire (Hertz) for $23.95 per day ($201.42.) The day I booked via Hotwire was August 29, 2010. Given all this, my advice is book a car now to insure that you have one, but make sure you know the cancelation policy. Then hunt for a bargain in mid to late August.
