He is a contractor on a per diem base - during his working on a project, he usually stays in places such as Hampton Inn, Comfort Suite that type - with the current promo from NW and the triple mile promo from Choice hotels, he is raking in 11,000 miles per week by changing his stay every night between 2 locations. 250 + 500 from Choice, 1000 + 1000 from NW because Choice posted the miles in 2 lots. Each night he rakes in 2750 miles!
I am tempted now eventhough I have 0 mile in my NW account. (the account was deactivated by NW and only re-activated a few days ago when I sent them email because I could not log in to buy tickets.)
