My story is:

wife will work for a project, company pays for Marriott hotels for 2 months.
she just registerred Marriott rewards account today, because company pays bill, so we focus on points, not lower price.

so my question is: where can we find some promotion codes that we can earn as many Marriott points as we can?

I am following some blogs, thepointguy summarize all summer pro here: http://thepointsguy.com/2012/05/hote...+Points+Guy%29

But it seems hassle because she prefers stay from beginning to the end, no check out during the 2 months.

I am familiar with PriorityClub, they have a lot of codes, when I fill in, I can get some thousands of bonus points...
I am not familiar with Marriott, so just wanna know is there any codes or any way that we can take advatange so we will earn extra points except for the basic stay points?

Thanks a lot.
