If you purchase a timeshare through redweek are there any restrictions put on the new owner from Marriott or do you you get full privileges even though you bought on the secondary market?

This article will have some answers to your question: Marriott Resales

You may be able to buy a resale directly from Marriott and get the same privileges as original owners. I know if you buy a resale from a third party, you will not be able to convert your week to Marriott’s Vacation or Bonvoy points. You will be able to use your week during the month(s) specified, and I’m thinking the “window to use” might vary a bit depending on the seller.
