For those having occasion to rent at MVCI properties, you can try, with no guarantees, a couple of codes I've used and seen.

MOD=Marriott owner's discount; I see both the 25% and 35%/VISA discounts, depending on property and dates. Never knew about or used it before becoming an owner so YMMV.

BWG=Buy X get one free. Saw this recently at Shadow Ridge for a buy 2, get the third free. Found on villarentals.com.
