In the terms and conditions - https://www.marriott.com/rewards/terms/usetrms.mi#redeemforanything - there is a section for customizing a reward.
I can't find it anywhere on marriott.com to actually submit a request.
I am trying to get a suite with 1 king and 1 double bed at a full-service hotel in Orlando (trying specifically the JW or Ritz near WDW) using points and this is not available on the normal reservations pages using points.
Anyone know how to use points to reserve a suite other than this mysterious customization link which seems to be hidden very well if it really exists at all?
Marriott customer service answered this for me. There is a link for elite members to submit requests for customized rewards here:
Why this link isn't anywhere on marriott.com is baffling. It's clearly stated in the Terms and Conditions, yet they hide it. I am not going to try it now, I ended up changing my plans, but if anyone else ever tries to customize a reward, let me know here how it goes.
