~~ Member Discounts ~~
***All discount rates are based on availability. There is no guarantee that any certain inventory or discount component will be available.***
Discounts for cash stays at the MVCI resorts (and very infrequently, at certain of the Marriott hotels/resorts) are capacity-controlled and based on ownership status:
Presidential and Chairman's Club DC Members - 35% off (code "2VC")
Executive DC Members - 30% off (code "6VC")
Select DC Members and Weeks Owners not affiliated with the DC - 25% off (code "7VC")
*MVW has clarified for TUG (see this post) that the Chase Marriott VISA 10% discount component is no longer available: "The Owner’s Discount can no longer be combined with any other discounts or offers."
*When checking availability on marriott.com, enter the appropriate code in the "Corporate/promotional code" box under "Special Rates."
*Owners may also book discount cash stays through the owners.marriottvacationclub.com website. Sign in --> click on "Owner Benefits" under "Partners & Specials" in the column on the right of the home page --> click on "Enjoy 25% off ..." under "Marriott International, Inc. Promotions" --> scroll through and click on "Explore" for the desired resort --> select "Corporate/Promo" in the dropdown menu for the "Special Rate Code" box and your eligibility code should pop up automatically when you click on the "Enter Code Here" prompt.
*Note the confirmations for stays using these discounts indicate that at check-in the certain eligibility will be verified. If unable to verify eligibility the cost for the stay may revert to rack rates.
