How do you add your Marriott Rewards number to your Reservation?

I'm renting a studio at Marriott's Ko Olina Beach Club in Ohau and was wondering how I add my Marriott Rewards number to my reservation. I'd like to get credit for the seven nights I'm staying there. I look forward to hearing back from you. Thank you.

Once you have an updated confirmation with Your name on it. You should be able to call the resort and have it added. They should be able to direct you on how to update this information. (All info is subject to change and verification. The resort should be able to provide the most up to date information as possible.)
