Mine is extremely easy but not very rewarding...
1 - Stay at any IHG® hotel and receive 1,000 Points.
2 - Stay a total of 4 nights and receive 4,000 Points
3 - Stay at 3 different IHG brands and receive 10,000 Points
4 - Book 2 separate stays through an IHG® hotel website and receive 2,000 Points
5 - Stay 2 Saturday nights and receive 8,000 Points.
6 - Complete all of your offers and receive 25,000 Points
50000 points in total + the points from the stays themselves. Not too bad in fact for 4 nights.
