We arrived about 2 hours before it opened and we were the only ones who arrived. However, we were able to park the car and wait in the car with the heater of course. We fell asleep for a while and when we woke up, the queue at the gate was already quite long. Fortunately, the queue for those who already had online tickets was only a few. Finally, we were able to queue immediately and had the opportunity to queue to see the penguin show in a strategic position.
