Windsor Castle: The mystique of eight successive royal houses of the British monarchy permeates Windsor, where a fraction of the current Queen's vast wealth is displayed in heraldic splendor.
Mapledurham House: While at this house that inspired "Toad Hall" from The Wind in the Willows, you can picnic on the grounds and drink in the views of the sleepy countryside.
Oxford: While scholars' noses are buried in their books, you get to sightsee among Oxford University's ancient stone buildings. Be on the lookout for gargoyles around New College: the evil little creatures are wickedly creative. Try your luck at punting, too. You'll either proudly exhibit your balance and strength, or take a humiliating plunge into a slow-moving river. Every big splash is greeted with a cheer by the students lounging on the shore.
Blenheim Palace: The only British historic home to be named a World Heritage Site has fine 18th-century architecture, stunning gardens, and remembrances of Winston Churchill. For a memorable treat, attend an outdoor summer concert.
