Just got an email, that i have got tickets for the audience, does anyone know if they are guaranteed seats or a first come basics.

Just don't want to waste my time going and not getting in, thank you.

First come, first served unless you have priority. Be prepared to wait. Last year Simon was 3-4 hours late and we had to stand outside waiting for him in the freezing cold. Only good thing was that they issued tickets with out seat numbers on, so we didn't have to queue the whole time.
