I rent a half dozen times a year at MIA Hertz - the new rental center is a big improvement. Sometimes I have had the feeling that the cars are a little less spotless than they should be. Never a problem with the Gold board - avoiding the lines is a big plus. Just be a little careful on returning - you drive around what seems like 5 circles before you go up a ramp to the returns. Slightly confusing, but a lot safer than having to cross the traffic like it used to be.
