An increasingly popular destination is San Juan Del Sur in Nicaragua; it is located in North America(yes, Central America is a part of North America)

Another location could be Bilbao, Spain. The city features modern and "kitsch" architecture, and the Guggenheim Museum Bilbao. 

Buenos Aires, Argentina is dubbed "The Paris of South America."

I don't know any websites or resources for finding 'great vacation spots.'
