Yes, I went to their residence by mini bus, there was a road in the middle, we kept looking around inside the bus through this road. However, the car was very sturdy and the windows were made of thick glass which would not break easily. I can assume it is safe for everyone.
No, I did not stay there at night, but this park closes after 6 pm. However, there are hotels outside the park to stay in, but we did not stay.
