Columbiahalle balcony

Hi all, I’m going to the sold out SpiritBox gig on Saturday 15th (I’m from the uk) and I’m going with my partner who is 5 foot so really struggles at some gigs to see the stage.

Can anyone please tell me if the balcony is ticketed seating or can we just go up and grab a spot?

Or if anyone can give me a heads up of a good area to stand so she wil be able to see would also be great

Thanks
