Ok, just got done talking with them.
Basically, Optimum (according to the Optimum person I talked with) is for corp accounts that spend a minimum of 100k per year. I guess they give this status to the head guy of the corporation. There would be no way for an individual person to spend that kind of money in a year (that's like $300 a day).
I asked her if they did any such thing with individuals who spend large dollars with Budget (i.e. like HErtiz and the Presiden't corner status) and she said nope, rather rudely.
So be it. Hertz here I come.
