Okay, I clicked on the button and it show a picture with 3 MIB guys holding a case and have 4 different boxes pointing to it. Here are the detail of each box:
1) TAKE A SURVERY -- EARN 2,000 BONUS POINTS
2) STAY 68 ROOM NIGHTS -- EARN 12,8000 BONUS POINTS
3) STAY 38 PROPERTIES -- EARN 21,700 BONUS POINTS
4) STAY 5 SATURDAYS -- EARN 3,300 BONUS POINTS
Mine's
1) 2000 for the survey
2) 1700 for 12 room nights
3) 2200 for 4 brands
4) 1700 for 3 saturdays
66,000 if you unlock all 4. Must be dependent on your current stay pattern i guess.
And the T&C say they can overlap i.e a saturday stay counts towards unlocking case 2 and 3 as well.
