Concern is growing in Historic Greenwich that the town centre on Millennium Eve could be something of a disaster area. At a World Heritage Site briefing last month, local people were warned about numbers invading the borough on millennium eve. Safety and crowd control might oblige the council to cordon off the town centre and Cutty Sark waterside and - as is done in Edinburgh - limit entry by issuing permits in the form of wristbands to locals and manageable numbers of visitors. Concern was also expressed about publication of wrong information. The Times recently referred to a public event in Greenwich Park - which will in fact be closed, except to TV crews. Prospective subscribers to an £800 cruise liner trip from Dover are being told they will see fireworks, but as yet there is not a single confirmed firework display in Greenwich, and it is apparently now too late to arrange one, because all firework contractors are fully booked for Millennium Eve. So are suppliers of portable loos. For visitors caught short in Greenwich, any talk of damp squibs may seem in poor taste.
