Heh, I didn't know AutoSlash had a CDP
Where did you find PC# 168210? I remember using it many, many times in the past, but I had no idea it still worked. This isn't a bad PC and saves you up to $35. Also, is the $40 booster seat a benefit of the AutoSlash CDP? With Amex and airline CDPs the cost is higher ($83.93)
I included the booster seat cost in all of my research. The Amex CDP and different airline CDPs all yielded the same rates. Here's what I found:
ECAR: $534.09 pay-now, $562.02 w/ PC# 168210
CCAR: $546.79 pay-now, $576.98 w/ PC# 168210
ICAR: $559.52 pay-now, $591.94 w/ PC# 168210
Looks like you're best off sticking with the
AutoSlash rate ^ $528 is a
very good rate for a rental as long as yours, especially at HNL.
