Two $400 gift cards and a $250 gift card will earn the maximum allowable 5000 United miles per member account during the promotion period.
As I explained in “Quadruple and Quintuple Dipping with Marriott” you can choose to earn Southwest Rapid Rewards points for Marriott gift card purchases instead.
Then make your Marriott reservations through your favorite shopping portal, like the Chase Ultimate Rewards Mall. Earn points for the stay and the credit card spend. And also earn a credit in Marriott’s free night MegaBonus promotion.
MegaBonus and the gift card components of all of this offer-stacking are the limited-time components.
