Marriott allows their Platinum elites to take advantage of Buy One, Get One (BOGO) weekend nights and half-off dining options at various properties throughout the year. These promotions usually happen from March to June, June to October, and October to January – participating properties vary throughout the year.
The current offer is for weekend stays from March 11- June 5, 2011. While weekend nights are generally considered Friday and Saturday, you may be able to use these for Thursday/Sundays if the hotel codes the night as a weekend rate. To book a BOGO night, you have to call the Platinum elite line and then print the coupon to ensure the hotel comps the free night.
