There are no advance tickets for sale anywhere.

There is a pre approved list of known people.

It is selective entrance, im sure you will have no problem if you come presentable.

This is to ensure good quality as it is in any other place, if you deem yourself to be this then im sure you will be fine, it's not going to be as strict as crystal or pearl for example but it will be along those lines.

There is a diplomatic way to handle every situation.
