The time depends on the no of car waiting in the queue. First time we went around 6.30 pm and the it was a long queue and we bailed out. The second time we did not take any chance and reached there before time. My friend had similar experience and the crowd has been steady and long now adays, this is the safest outing considering the current situation. My suggestion is to reach there ahead of time to reduce your wait time.
I dont know but I wouldn't want to find out. We got there at 5pm and we waited 30 minutes to get in.
