我的任务：六个任务达到五个即可！
大奖：24400 or 2 free night
1. stay 7晚 (9200 points => 太多了，当然是放弃掉这个)
2. survey (100 points)
3. spend on your IHG credit card (1500 points)
4. Stay at 2 Holiday Inn Express hotel (4800 points)
5. Book 1 stays using the Bonus Points Package with breakfast rate
(2000 points)
6. download APP (8000 points => so easy)
TOTAL：16400 points + 2 free night
虽然奖励不怎样，但是我的任务很简单，
总共只要住两晚Holiday Inn Express，其中一晚选package with breakfast就好
成本... 哈哈哈，只有两晚...鸡毛蒜皮，我就不计算了XDDD (我知道有点欠揍XD)
