Booking the itinerary directly on Klook is very convenient. After gathering at the Kowloon Hotel, the tour leader takes attendance and we board the bus. Then we head straight to take the cable car. Moreover, we use the group ticket fast pass, so we don't have to squeeze in line with the general ticket holders. The scenery on the cable car is amazing, you can see the entire airport scenery and the Big Buddha from above. Highly recommend this itinerary!
