Yea I'll have to hold my hands up here, I got it wrong. The Radio 1 event is free, you'll just cue for tickets on the day, first come first serve basis. The Radio 1 party will finish at midnight local time and then the come together party will carry on in Space for which you will need a ticket for at 40e a pop.
This has led me to think about something else though. Where do you think they will actually hold the Radio 1 party at Space. Do you think it will be in the car park as someone has already mentioned? I think it might be because for starters they can errect a big stage for all the live acts to perfrom on. Second, if they held it inside space in the Terrace or main room, how would they then get rid of all those people who didn't have tickets when the Radio 1 event finished leaving all the people with tickets in the club? They would have to clear the club and then let everyone in again who had tickets. That just sounds like it would be a logisical nightmare therefore has led me to believe that the Radio 1 party will be outside in the car park, then the come together event will continue inside space which you will then need your ticket for to get in.
Please feel free to comment if anyone has any other suggestions.
