The agency is looking at adapting a youth campaign already planned for next year to tie in with the wedding.
A spokesman for VisitBritain told Marketing today: "We’re on the ball. We are at the forefront of marketing this event to leverage inbound tourism to Britain."
Sandie Dawe, chief executive of Visit Britain, said this week: "It will give VisitBritain a wonderful opportunity to showcase Britain in the lead up to the 2012 Games.
"We are already talking to the rights-holding broadcasters and the marriage in 2011 gives a further unparalleled chance to tell the world what we have to offer as a tourism destination.
"The Royal wedding is going to deliver an enormous boost not just to the tourism industry in London but across Britain."
Thirty million tourists visited Britain last year, generating revenue of £16bn, according to the agency.
