Accruing points and miles is therapeutic - I would even go as far to say that it is even more satisfying that watching your savings grow. From now until 19 May 2017, benefit from 100% bonus IHG Rewards Club points when you purchase using this link. If you were to purchase the maximum number of points allowed (60,000) in a calendar year, you will get 120,000 IHG Rewards Club Points (after the 100% bonus) for US$690 (S$963) which may offer great value at a number of InterContinental properties in the region.
If you do have a number of planned stays coming up, you should definitely register for the Accelerate offers and the Book Direct promotion to benefit from even more IHG Rewards Club Points. I would probably not advise you to buy IHG Rewards Club Points unless you have an immediate use for it - these points offer terrible value in Singapore properties so you should definitely look at using them in more expensive cities like Hong Kong or Japan where you could potentially benefit from a lower equivalent rate when paying by points.
You may also convert IHG Rewards Club Points to airline miles at a 5:1 ratio - be sure to check out the 50% bonus on Alaska Airlines Mileage Plan Miles to get cheap premium cabin flights!
