I want to know the answer to the following question:
Northern Greece gets how many visitors?
All the background I'm provided with is that "The vast majority of visitors in Greece in 2007 came from the European continent, numbering 12.7 million, while the most visitors from a single nationality were those from the United Kingdom, (2.6 million), followed closely by those from Germany (2.3 million).". Is that enough to answer the question?
