I want to know the answer to the following question:
What have a number of tourism-related organizations placed Greek destinations at the top of?
All the background I'm provided with is that "Lonely Planet ranked Thessaloniki, the country's second-largest city, the world's fifth best "Ultimate Party Town", alongside cities such as Montreal and Dubai, while in 2011 the island of Santorini was voted as the best island in the world by Travel + Leisure.". Is that enough to answer the question?
Answer: no
