I'd add to this that if you're concerned about someone trying to break into your van (with good reason possibly) - there's an open-air car park with a security hut manned 24/7 there too, on the site of the old Boddies brewery (corner of Great Ducie Stree and Trinity Way). It'll cost you a few quid obviously. If you park up out of the way and are reasonably discreet the staff won't hassle you while you kip in your van for a single night.
PS: If you're having a few beers be *very* discreet about street parking - if you attract the attention of the police and you're over the limit you'll very probably end up being done for 'drunk in charge' and losing your licence even if it's bloody obvious you have no intention of driving the van. There might be a slightly higher police presence in that area than you expect if there's a gig on at the arena.
