"There are countless stories of guests getting IDs checked, in some cases needing a special company letter or requiring a company fax confirming the reason for staying. Park Hyatt Sydney reportedly liaised directly with the company travel desk — one guest who resigned had their upcoming booking cancelled because they were no longer authorised to use the rate. Hyatt is noted as quite strict about checking identification, especially in Asia and Europe."

"I can inform you that if someone checks into the Park Hyatt Sydney on a discounted corporate code, and I try to book a revenue stay, my rate will be higher than had they not used the code in order to stabilise the average room rate. This will occur at all Hyatt properties that operate with a floating rate of the day based on availability. So it does indeed affect you."

"Just wanted to let you know that I tried using this code at Hyatt Regency Istanbul, and the guy asked me for ID. I explained that I was a contractor, but he wouldn't buy it and requested further verification. I told him to just charge me the regular rate, and I would get reimbursed. It was only a 25 euro difference per day."
