Look at some of the tour packages, eg Hokkaido 7 days, The Silk Road 12 days, 10 days Egypt, 11 days NZ, all are around 5k. So, each couple could very well be >10k..
10k for travelling? Yes, I would, but may be once every 5 years or so, a treat to my parents. Other time just go budget independent tour..
So far, has only brought (belanja) my parents to Tasmania, 8 days, SGD 7k...
Will you spend 10k to go traveling? (Travel)
