I've rented at multiple locations and have always checked using a number of CDPs to cover my employment / association -- this includes; HP, Dept of Defense (retired military), AARP, AAA etc. I always thought the lowest was the military which seemed to be pretty true for many locations, but in MCO, BOS, PHL, BWI - a couple of my recent destinations I've found that actually my work CDP from HP nets a lower rate. (Although I also found out that you don't earn any Hertz #1 Awards with this rate).

Can anyone else offer their comparison - what have you found to give you the lowest rate?

Thanks.
