London (Greenwich), England
Discover the celebrated Royal Borough of Greenwich—part of which, Maritime Greenwich, is a UNESCO World Heritage Site. London is just a short drive away, so you can take in the regal city and all its splendor. See the Tower of London, Parliament and Big Ben, Westminster Abbey, Buckingham Palace and St. Paul’s Cathedral. Or venture into the countryside to visit Windsor Castle, one of the royal residences. Alternately, step off the ship to tour Greenwich, its excellent National Maritime Museum and the Royal Observatory from where the world’s clocks are set.
