On Tuesday March 24th Marriott Rewards launched the 3 for 2 Resort Redemption Special.
With this limited time award, members who redeem for three nights will receive the third redemption for free at 55 participating Marriott Resort locations.
Here is the list (http://www.MarriottRewards.com/3for2Resort) of participating properties.
The stay must be completed between March 24th and September 7th, 2009. When making your redemption reservation you must request the 3 for 2 Resort Redemption Special Certificate. Please note these rewards can only be issued over the phone.
A recent New York Times article suggests this promo, may get two nights free on a 6 night stay. I am not so sure. But you need to phone anyway to reserve so check it out if it fits you.
This promotion makes up for the recent increase in redemption rates.
