Ahoy (Netherlands) 6th of december --- How late should I be there?

Hello Pink-fans!

I'm going to the Funhouse concert in Ahoy (Netherlands) this december! but I have
no idea how late I should be there... I have standing tickets and I'm going
with my sister. The show begins at 8.00 p.m.

Please help me with this because I want to be one of the first there!!!

ps. if you read this and want to go early too comment (maybe we can go with a group!!)
