It makes absolutely no difference at all whether you go with Dollar or Thrifty. They are basically the same company. They have essentially the same fleet. Dollar has
Dollar Express and Thrifty has
Blue Chip. Neither is particularly good as compared to similar programs from the major brands, but they certainly can't hurt and
might help speed you on your way.
Sometimes though, one may have a better coupon or discount code available than the other, which can make one a better deal, so it's worth submitting a quote request to AutoSlash to check pricing across-the-board.
Also keep in mind that pricing can change over time. You might find that prices with Hertz will drop at some point, so it might also be worth booking a pay-later reservation and tracking it with us just in case there is some jockeying for price as the pickup date approaches.
