Top 20 Cities for Tourists: Despite its high price—the pound is strong, making it one of the most expensive places to live and to visit—London continued its dominance in the tourism industry. Some 18.7 million tourists came through the British capital in 2014, putting it more than two million people ahead of its closest competitor. It also comes in at no. 1 in terms of total visitor spending, with tourists spending a grand total of $19.27 billion in 2014. That is a lot of cups of tea.
