Going to be in Vegas in a month and car rental prices are nuts. Wanted a car between Mar 1 at noon until 10pm on the 5th. Best rate I got was $190 for a fullsize car through Total Rewards for those dates when I checked 2 months ago. Held off hoping they would fall. Prices on all sites fluctuate daily but now the cheapest was $400 for the same car and duration. Have checked TR, Costco, Hotwire, Expedia and the agencies, etc. Last March through TR we had a car for 6 days costing $104 total. Double this yr is steep enough but 4x the amount seems insane for a week that isn't very busy. Any tips from the pros for hunting for a better rate? Maybe clearly cookies or using a different computer will yield a different result? Wife really wanted to do Red Rock, Hoover and Neon Boneyard this time. Any help would be appreciated.
