Passengers can choose among four types of cabins on the double-decker bus, with tickets prices ranging from $13 to $51. The itinerary offers a "food coma lunch" and stops at various scenic sites and drop-off locations.
Passengers meet at a restaurant for a two-course western meal before boarding the bus to start sleeping. Stops include Ho Wo Street, Butterfly Beach, Tuen Mun Chek Lap Kok Tunnel and Inspiration Lake.
The sleeping bus tour was sold out for its inaugural trip Saturday, NPR reported.
