Hi

I am going to Santa Maria on 19 December via the Kosi Bay border post.
I have never used this border post. I know that it will be very busy during this period.
What is the best time to arrive at the border in order for me to be as far ahead in the queue as possible? It is a hell of a drive from here to Santa Maria so i would like to get the formalities over and done with as quick as possible.

Thanks
