It is unlikely anyone will be able to see Tom Cruise and Katie Holmes say 'I do' this weekend as even with a helicopter peeking into the Odescalchi (pronounced: oday-skalki) castle is virtually impossible. Noone knows how the couple will arrive, by helicopter or car, and now the locals are even saying they could arrive from the other side of the lake by boat and then drive up to their medieval wedding venue. The couple themselves have remained hidden since arriving in Rome at the beginning of the week. The only real excitement having been the arrival of the supposed Giorgio Armani wedding dress at their hotel on Tuesday. But Italian media and the odd fan have mounted a round-the-clock vigil outside the hotel Hassler where the couple, along with a bunch of guests including top Hollywood names, have been holed up. The only thing for certain - sooner or later they have to come out.
