"Hyatt corporate codes as a category are documented on FlyerTalk: "You'll read countless stories of folks getting their IDs checked, and in some cases finding out that they needed either a special company letter or someone from the company to fax in their reason for staying there. There have also been some asks such as needing to have your company badge on hand." No BMW-specific Hyatt denial case found, but Hyatt is noted as stricter than Marriott overall."

"I have a reservation in DC this weekend (11/14) and the LTO110 code showed up for it when I rechecked availability/rates. A call to GP customer service verified the rate and dropped the price 10% below what I'd previously booked. It does require a bit of clicking about on the site, but it's there. Under 'reservations', hit 'specials & packages', then the 'hyatt special offers' tab. The link to the LTO110 rate is the fourth one down."

"I mean, you can book the rate, but 100% PH Tokyo requires proof of employment. I had to email from corp domain and provide a business card (Dec 2022). If you show up and can't provide proof of employment, either you'll be paying a very expensive full price for your stay, or they'll invalidate your reservation."
