Here's another vote for renting a car.

I'll be in Vegas 18-26 June and am renting a mid-size for $12 a day from National Car Rental. Instead of booking through your company, try this: go to Hotwire and see what prices they quote you for your dates. Then go to Priceline and bid $2-4 less per day than the lowest Hotwire price. This has worked well for me every time I have done it, and always beats any other deal I could find (even beats "stacking" discount coupons directly with the rental companies).
