I own two Marriott Aruba Timeshares, one is a Platinum Season, 2 bedroom at the Surf Club and the other a 1 bedroom Gold season at the Ocean Club. I have on a few occasions deposited a week that I was unable to use into Interval with no success ever redeeming that deposit for a comparable week in Aruba in return. What I have done successfully is this. I book my week at my Marriott home resort (Surf or Ocean Club) and receive the confirmation number and then rent that week through Redweek at a reasonable rate that covers my Marriott maintenance fees. This eliminates all the frustrations with Intervals redemption system . You can then use that money to rent a week from other owners that post their weeks on Redweek. If you decide to rent through Redweek , look into the premium service option and they will mark your posting as Verified and will process the payment transaction between you and the renter eliminating any worry of fraud. If you own a two bedroom lock-off villa like I do at the Surf Club, you could request that Marriott break the full villa two separate reservations . This allows you to rent both weeks as an option for even more money.
