How I enjoyed walking in the garden of Drottningholm castle and Versailles castle! Glad to live now and not then - especially as a women. The parks are free to enter and to observe the changes of the seasons. Here in Drottningholm it is a smaller area then in Versailles but enough for a long morning walk.
This castle is like a miniature of Versailles but the King and his Queen are still living in the Western wing. the Eastern wing is open for visitors. Swedes do not mind the Royalty as long as they do not get politically involved. http://whc.unesco.org/en/list/559/
In the Royal Theater they have always their reserved seats available.
