UK tourism chiefs have been urged to start now to ensure the 2012 Olympics generate billions for the economy.
Lord Coe and Tony Blair met leaders of major tourism groups
Tony Blair, Culture Secretary Tessa Jowell and London 2012 chairman Lord Coe met leaders of major tourism and leisure groups at Downing Street.
Bosses from the Hilton group, Center Parcs and others were told quick action could lead to a 25% growth in tourism.
Ms Jowell said: "It can grow to £100bn by 2012 with action on skills, quality and investment. But we must start now."
The meeting discussed raising accommodation standards, access for disabled visitors and ensuring workers who looked after tourists had the necessary skills.
"By starting now we can make sure the value in some cases is immediate," Jowell added.
The government also said the Games would provide benefits for the whole country and leave a legacy in terms of tourist facilities.
Brent Hoberman, founder of lastminute.com, said the emphasis was on "brand Britain", regulation and what more the government could do to co-ordinate things.
"That it is a very important part of it that the public and private sectors are working together on this and they are not in competition," he said.
