I am in the same boat as some of the others, a lot of long rental but could not be happier with the switch from Hertz to National. A lot better selection of cars and when you do use your free days you can use them for nicer cars. Just used some old hertz points the other day, reserved a premium car, got a plan Maxima with 51k miles, and this is as a PC. Hertz also changed from a very few black out days to A LOT. Try getting a free day in FL, almost the whole year is blacked out.
