Culture takes center stage in cities everywhere, each offering its own unique flavors, art, theater, dance, music, architecture, literary heritage, and history. A great city vacation might include seeing a show, snagging reservations at a trendy restaurant, museum hopping, market shopping, and scoping out urban parks. From North American metropolises teeming with international flair to Asian conurbations known for their mouthwatering cuisine, and the nature-surrounded nerve centers of South America to the historical hubs of Europe, the wildly diverse cities of the world are ripe for exploration.
