We have a confirmed $177 rate for 8 days (Saturday to Sunday) from Dollar rental, taxes and fees included ($22 a day rental isn't bad) for an AMERICAN full size car. I agree 100% with Ross' post. Yes, once the convention begins, the car we rented for the week probably won't move from the SP parking garage but if you want to get around town, or sightseeing outside of town at your convenience, one must pay the going price.

*We just got an outrageous $400 weekly car rental quote (Friday to Friday) for our Nashville trip later this year so $177 in Vegas is a bargain.
