I have a reservation coming up in a couple of weeks at Embarcadero in San Francisco. I used the Deloitte code A442100 to make the reservation, and got the email warning about using corporate codes, etc. I did used to work at Deloitte, and even have my business cards from there. Wonder if that's enough to pass muster..I never used the code before or rented at this location - so not sure how strict they are. Does anyone have any experience there?

What someone mentioned above in the thread was concerning to me - if there was an accident, I would be concerned that I would not be covered if I used that code. It doesn't look like the Deloitte code includes insurance - so maybe that's only a concern for those types of codes. But if that would happen, I think it could be worth paying some more to avoid any issue down the line.
