London, England (CNN) -- Speculation was intense Friday over where and when Prince William will marry Kate Middleton, with many predicting the couple will choose the iconic, thousand-year-old Westminster Abbey.
Middleton was photographed leaving the abbey Wednesday night with her parents, and British newspapers reported they had a private after-hours tour.
Westminster Abbey is the "venue of choice" for the wedding, the Daily Mirror tabloid reported Friday, and it even published a seating plan for the big day.
Ladbrokes betting agents seemed certain Friday that Westminster Abbey would be chosen, giving it 1/33 odds.
