Thanks for the reply. We've been members here for many years and have always been able to rely on the members here for great advice. I allowed my membership to lapse about a month, so my profile does not reflect our past activity.
We have made many trips to Las Vegas over the past 30 or so years and always been able to find very reasonable car rental rates, in fact many absolute bargains. This year seems to be very different. The prices I am getting are quite astounding. I did notice that the taxes have become a major factor in the pricing. We know to keep checking back, and we do, even up to the day before traveling. I suppose it could be our dates just after Christmas and before New Year's Day when activity begins to pick up again out there.
We'll continue to keep checking. If anyone has any codes for Alamo, Dollar or Hertz please post them here.
