I recently went on vacation around Europe, I started my trip in Paris, France and stayed for 2 Days,

I then ventured Marseilles, also in France for a further 5 days,

the third portion of the holiday took me to Venice, Italy where I spent 12 days,

I stayed in my penultimate location, Vienna, Austria for 16 days.

The final leg of my trip took me to Sophia, Bulgaria. How long did I stay?
