Accor, who owns are slew of hotels, including Pullman and Sofitel, IBIS and Novotel, are running a pretty simple promo who can earn about 1,050 points. That would take you just under half way to their 2,500 award.
When you get to the page, log in to your account and then click through the various tiles on the page, answering the questions, visiting the pages linked from the tile and signing up for their newsletter. Each tile gives a different number of points but if you do all of them you should get the full 1,050 points.
A good way to spend five minutes on a Sunday.
