Woke up this morning and saw a new promo in my account:
Earn 1 free night after 3 qualifying stays
Key T&Cs:
Marriott Rewards members who register for this promotion by June 30, 2009 will earn one (1) free night award at a category 1-4 hotel after their third paid stay made between June 1, 2009 and August 31, 2009, at a participating Marriott property.
Maximum one free night award earned with this promotion per member.
An earned free night award can be redeemed for a future stay at participating Marriott Rewards category 1-4 properties for one (1) free night between June 1, 2009, and December 31, 2009.
An earned free night award is good for one (1) single or double occupancy standard room only and includes the cost of the hotel room and applicable room taxes only.
An earned free night award will be added to the member’s account within 3-5 business days after the third qualifying stay.
Awards are not transferable and may not be given as a gift.
This offer is not transferable.
Sounds like a nice offer, but I'm a bit disappointed that only one free night can be earned (seems less lucrative than other programs), but it's nice that the night can be used through the end of the year.
