"Also depends how the management company or if it’s a corporate company actually trains the front desk associate. For example, some agents are required to ask for your government ID to get the perdiem government rate which is usually heavily discounted if offered at the hotel. I’ve worked at various hotels each with varying policies. One hotel might have a front desk team that’s more trained to ask for ID’s or proof in order for you to get that rate. Deloitte, Accenture, Kaiser etc all have corporate negotiated rates that come with steep discounts and perks. For example Kaiser usually had a lower rate, discounted parking, lounge access etc. It’s not hard to obtain these corporate negotiated codes so that’s why some agents will ask you for proof that you work for said company. It’s not personal they are just doing what they are supposed to do."

"I now always make it a matter of course to carry documents (business cards of my contacts, e-mails requesting my visit etc.) from my host company when I travel. This has always proven sufficient for the few times I've been challenged by the front desk clerk."

"I have stayed 100s of times with various corporate rates (including Japan) and the only hotel that has asked is W hotels. Even then they didn’t push much. I have been a consultant for 20 years and many clients require you to use their rates when they are paying the bill. The hotel doesn’t have an up to date list of every employee that works for a company globally. The woman at the W said “I don’t really care, just show me anything on your phone that says your name and that company. You can type an email now “."
