If necessary you can pay in cash on the night but obviously we'd prefer if folk paid via meetup as we won't be carrying change or taking many on the spot payments.
Is the number of attendees limited? If so, I'd like to somehow book it.
Technically it's limited to 400 and we usually reach that figure however we have 'emergency capacity' for an additional 200 so I promise you won't have any issues getting in. Drop me an email (info in my profile) and I'll give you my mobile number so you can call me if you have any issues at the door and I'll sort it.
This event has traditionally booked up fast, although the new (modest) fee has helped slow down the rate at which that happens. I wouldn't wait too long.
