Better off using Klook and forget about the miles
Booking process is cumbersome and platform is not user friendly. Lack of options and difficult to find what you want. Lack of reviews and prices are more expensive than Klook. Reporting issues is a big hassle and customer support is no help at all. Totally waste of time. The quality for the price you pay is totally not worth for the miles earned. Airport transfer I have booked this time was by far the worst I have experienced.
