There was some talk the other night about the price of the tickets having gone up considerably. Someone also mentioned that they were cheaper in advance. I had a look and the website (http://www.salute.co.uk/salute/salute-2016/tickets/) says this:
Tickets on the day will still be available via the online system £12.00 Tickets on the door (CASH ONLY) will be £20.00 Group Tickets are available; Buy 10 tickets, get one Free (Shown as buy 11 tickets at a reduced rate £10.90) Under 16's are free to enter when accompanied by a paying adult
Definitely worth using the online system it would seem!
(I am smug, though, 'cos I'll be getting in for free - hurrah for demo'ing games!)
If you don't mind a bit of a walk (although Excel is so bloody big, it's a bit of a trek even to parts of the underground car park), this website has a bunch of places local to the venue that are much cheaper (assuming it is to be believed). www.justpark.com
