Apparently I have more than one account now that they have taken over Starwood. I was told by Marriott Rewards customer service to link them but can't figure out how.
firstname.lastname@example.org, follow the link below, sign in, and it will instruct you on how to link your existing Marriott Rewards and Starwood accounts. I am assuming that you only have one of each. If, per chance, you have multiple accounts of either, you will need to call the Rewards hotline to combine those accounts into one prior to linking your Marriott and SPG accounts. I hope this helps!
