Ironworks, 30 Cheapside, Brighton, England, BN1 4GD, United Kingdom.
The venue is less than 5 minutes from the main Brighton station, with direct rail links from London Bridge, Victoria and Gatwick. For rail information visit National Rail Enquiries.
At the weekend, many places in Brighton require a two-night booking. So it might make sense to book the Friday and Saturday night. That way you'll be rested for the start of the event and able to attend the after party!
There are lots of hotels and B&Bs, but there are also some great Air BnB options as well.
