I guess the topic has been discussed a few times at FT but the view seems to be divided.

So, I am going to join a company in a month and through a friend, I know of the corporate rate code. I plan to book a Hyatt hotel using that code - does the offer letter make me eligible to use it. If not, can the still hotel create a problem if I show them my offer letter and email from the new employer?

The hotel is in India - does that increase the probability of the hotel asking for stricter documentation (company ID/ business card)

Thanks!
