You’ll need to enter the company’s specific Marriott corporate code in the special rates tab for the corporate discount to apply.
Navigate to the Marriott booking page, Simply navigate to the search bar and expand the column titled “Special Rates”. You will see a dedicated section titled “Corporate / Promo / SET#” and here is where you will want to enter your corporate code.
After you have entered your destination and travel dates, click on the Corporate/Promo Code circle and enter the relevant Marriott corporate code. Then hit “Find Hotels” and the hotels that are offering that rate will show up.
