Oooo! Oooo! Can I come?!

Seriously though - presumably there will be enough space and everything; but will there be a charge on the door? If not, will it be possible to donate to YAS / Perl Foundation there, or do we have to be organised enough to do it anyway? :)

I'm hoping to bring a cow orker who is currently getting into Perl, and it's London ferchrissakes - we expect to pay.
