I would like to see the sunset from the Khalifa Sky Observatory at the 148 floor. Visit is on Monday 3 Apr. Sunset is about 6:30pm, To be on the safe side with the queues I'll plan to buy the 5pm ticket slot.
The page says "the visit may last upto two hours". When do the 2 hours start, when you reach the top or the ticket time, means I have to leave by 7pm?
