Trip is in a couple of days. Prices have climbed <for me> more than they have dropped as I got closer to the rental. Had the cheapest "consistent" price about three weeks out. Since then, they have just gone up.
Luckily, I managed to secure an $83 rate (all inclusive) around the latter part of June, I believe, for a five-day full-size car rental, including additional driver and unlimited miles from Hertz. That rate was only around for a very short period of time, as far as I can tell (I was checking daily, saw it, booked it, and three hours later, it was gone).
I do have some fairly good codes, etc., esp. with National, but with the additional driver and all, nothing beat this. And, the big surprise, was I just used the Hertz Disboards code and an $11 promo coupon that I had picked up somewhere.
Anyway, best of luck to you who are still looking -- I give up --
