I just redid my Alamo reservation - I was able to get $225 for a full-size car for 9 days starting 7/22. I used my Costco rate (7014627), plus a coupon code (AD3868JST), and reserved with my Insiders ID. It was cheaper with Alamo than it was at carrentalsavers.com, but by only a few dollars. The Costco rate allows us the 2nd driver for free, which saves a ton for us. Never let anybody drive the car if they are not on the reservation! That will void any insurance you get from your credit card or
trip insurance.
I am a Costco member - I've been asked to show my card with Alamo.
