"McKinsey codes at luxury Hilton brands (Conrad, Waldorf Astoria) carry higher verification risk. One Fishbowl user was asked at a Westin SF for firm ID, resolved by offering work email verification. Hilton verification is hit-or-miss, roughly 20% of the time across legitimate corporate codes. Code is flagged in industry databases. Properties near McKinsey offices show heightened scrutiny."

"I know that previously the Hertz IBM rate was always fixed in the mid $30s for a full size vehicle with last car availability. A minivan was $175/week in Orlando even during President's week when the going rate was about $1,200. This is probably why Hertz and at least Avis has been more strict. I have found Marriott to be very strict, especially at key locations, when it comes to the government rate. Marriott wants travel orders, a government ID, and/or a government credit card. I found Hilton to be less strict for those government rates."

"I have used my corporate code multiple times and never once have I been asked for an ID."
