Far from the city, parking is usually clogged - it will not be possible to get up close to the entrance. Since this is a closed facility, a document confirming the identity is asked at the checkpoint to be recorded in the visit log. This is not a store or a shopping center - no one will meet and explain in detail, the services of customs brokers or SVH will be very difficult for an uninitiated person to find.
There is no shower, I have been standing for 4 Days waiting for customs clearance. Very hot. The toilet is very far away. I want to swim, but there is no shower
