Lisbon, Portugal★ Pin
Lisbon looks like Paris-on-a-hill, all pastel facades and tiled buildings, and travelers assume Western Europe pricing to match. It doesn't. Petiscos (Portuguese tapas) run $3-6 a plate, a day pass on the historic trams is under $7, and guesthouses in Alfama or Graça routinely go for $25-35 a night. Time your trip for shoulder season (April-May or September) and flights drop too.
