"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 also see a problem where (I know our company has for certain properties) Last Room Available rates which come in at the corporate rate; its not for all properties but we do have a list of those where if there is one room left, they have to give it to us at the corporate rate; other places is a certain number go at Corp rate 1 then it goes to corp rate 2 etc"

"I actually used to work for the Park Hyatt Sydney several years ago, in sales and marketing. Every year corporate rates are negotiated based on the number of room nights from the previous year. I can assure you that the abuse of these codes will not go unnoticed. While a chainwide code may apply, it wouldn't be difficult for IBM to see that rates were being used at a property they may not utilise, such as the Park Hyatt Sydney due to the high average room rate, and realise that the code was being abused. They will also notice a significant spike in room nights booked."
