We have done the day time hop on hop off bus tours before in KL but the night light tour was new. The selection of lights were the most famous - KL Tower, Petronas Towers, King’s Palace, British Colonial Buildings.
Overseas visitors paid more for the tour than Malaysian’s but the locals got all the seats in the open section of the bus.
Hence trying to take photos was difficult through the windows due to the reflection.
Also, it was stated if you left your seat anytime, anyone could take it, so no one in the open section of the bus got off at any of the sites. Overseas visitors had to get off the bus to take decent photos.
The advantage of the tour was the convenience of being taken to the sites rather than catching a taxi or grab.
A better idea would be to have two buses one for locals and one for overseas visitors.
