Most Sold Hostels Worldwide January - March

Hi, 

I'm Seeking Information to Compile a Data for a Travel Company Client, which is looking for the Information which Hostels are Most Booked or Sold in the Months of January - March with Solo Travellers on a Leisure Trip. 

- These Indicators will Help me Correctly Focus on the City and the Other Attributes that Solo Travellers are Engaged in. 

Early Response will be Highly Appreciated.
