"FlyerTalk's landmark thread "London Hiltons now requesting corporate ID if using codes" (2022-2023): "Just a word to the wise. London Hilton chains are now requesting corporate ID if you are using the discount codes." A second user confirmed: "I have been asked for Employment ID for the first time in London this year too, and multiple times so." The stated policy: "show a company ID card, or pay the full walk-up rate." Community-wide Hilton estimate: "hit or miss, about 20% of the time." UK/Europe properties have meaningfully tightened since 2022 — P&G's Hilton code N0000537, as a globally-used corporate code, is precisely the type flagged in London and other European cities."

"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 don't know what will happen if these hotels, car rental companies, or other providers start asking for corporate identification. It seems problematic. Hopefully it will be that only a few locations, of a few brands, are demanding identification and for a specific reason."
