No, just the opposite... With my corporate CDP, a full size is $1 per day more than a midsize, but a premium is only $8 more than a full size. Since I don't fit in any "full size" cars Hertz rents now, I am SOL if they don't upgrade me.
There are NEVER any Maximas or LaCrosses available for less than a $10 per day upgrade, so gold choice has proven to be of ZERO benefit to me.
OT: If the class creep keeps going at the current pace, soon I'm going to end up having to pay for a "specialty luxury" car to get a POS CVT car with 50k miles that has been smoked in! Sometimes it really sucks to be tall...
