There may be a Marriott issue here. From your posts, it appears that you own four Ko Olina intervals and intend to rent at least two weeks. That does not establish that you purchased them solely as rental inventory, but repeated profit-oriented rentals could be viewed as a commercial rental pattern. Marriott’s published Abound Exchange Procedures state that accommodations and use periods may not be used for a commercial purpose, including a pattern of rental or leasing that Marriott determines constitutes a commercial enterprise, and Marriott reserves the right to cancel reservations or impose restrictions:

How Marriott acts and what they determine may depend upon whether these are deeded Ko Olina home-week reservations or reservations made through Abound.
Marriott sales personnel may sometimes suggest that owners can rent unused time or recover maintenance fees, but an oral sales representation does not supersede the governing documents or Marriott’s current reservation rules.
You don't want to run into issues, I would suggest reading their policies, talking to people who have done what you are doing, and looking at options and risks.
