I would start by changing the present restricted hours opening hours so that the 'Cultural Centre' (as it was marketed initially) is open beyond 8pm on weekdays and 5pm at weekends. - without the present surcharge to pay for extra security. This would enable more people to attend after the working day, attract more events and greater community use. It could also raise more revenue to pay for the longer hours.
There is a real danger that restricted opening hours and poor marketing could undermine the potential of the centre. This is of course what happened to its predecessor.
