Milan was just named the number one place to go in 2015 by the New York Times. This year the city will host the 2015 World Expo from May 1 until October 31, so if you’re savvy enough with your booking dates you can explore the over 60 pavilions from more than 130 countries for the bargain price of an off-peak award ticket. You’ll have to fly in early May or late October, but you’ll save 20,000 miles.
