Good news if you’re planning to visit London for the Olympic and Paralympic Games: some of the capital’s biggest attractions have signed up to a new charter promising fair pricing during 2012.

The London Eye, Tower of London, The O2, London Walks, Eurostar and Tom Aikens are among those who’ve pledged to maintain normal prices during the Games. More than 30 businesses have signed up so far.

Mayor of London Boris Johnson said, “The London Visitor Charter demonstrates our determination to offer all our visitors both a great deal as well as a great time.”
