It sounds good but there will be traffic generation and parking implications and this should also be factored into the equation and needs to be dealt with somehow. (One of the major issues that defeated the multiplex aspirations of Bromley Council not long ago!) There is absolutely no real evening parking in Crystal Palace (the park closes, as does Sainsburys car park, unless this operates on extended hours ). I know people will say take the bus however thats not realistic for many people and not what really happens. At least Brixton and Clapham are densely populated areas with already excellent public transport links. If like me you've ever stood in the rain on Crystal Palace Parade on a cold February evening at 11pm waiting for the 122 bus, you will perhaps know what I mean!
