London 2012 Olympics: £27 million Opening Ceremony shortened by 30 minutes amid transport fears Organisers have always said they want to be finished by midnight or 12.30am at the latest, but the tube network will run until 2.30am in anticipation of an overrun. London's options are limited because the show, which will rely on lighting and fireworks for dramatic effect, has to take part largely in the dark. The major challenge is getting spectators and a high volume of VVIPS - more than 120 world leaders and heads of state are expected - in and out of the stadium's island site. The unfolding security shambles may have an effect on spectators accessing the stadium, but could be partially offset by encouraging ticketholders to arrive earlier ahead of the 9pm start. Getting them out again is less a matter of security than pure logistics, with the VVIPs and IOC members expected to get priority as they leave by road. The rest of the 50,000 or so spectators, sponsors and media will make their way off site by public transport or on dedicated buses. It is a hugely complex process that will provide a huge test of London's readiness. Boyle will be reluctant to cut a ceremony that he has been working on for almost two years. Volunteer performers have been rehearsing for months in largely foul conditions, and there is frustration that their work may be wasted. The irony is that whatever the logistical challenges, a successful ceremony that lights the imagination of spectators and the millions of people expected to watch in the UK and around the world, will buy London and enormous amount of goodwill as the Games get under way.
