First there was the Lady Diana walking tour of London. Now, just in time for the next royal wedding on April 29, comes the Kate and William walking tour offered by Celebrity Planet, a travel company in London. The tour is part Diana-and-Charles, with a stop outside the posh jewelry shop where Charles bought the diamond-and-sapphire ring for Diana that Kate is now wearing (one might consider this bad karma.)
The walk lasts 2.5 hours and costs $24 (15 pounds). There’s also a chauffeur-driven version for $120. As if.
