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?

Yes, It's hard to do because I don't have a good map that will show the location of all the cities on the same map. I've been working on straightline distances from Paris to each city, but the lines did not seem to have a direct link to the days. Then I tried to find a point where Paris, Marseilles, and Venice produced lines that corresponded to 2, 5, and 12 respectively. Did not work out. But it looks like your east theme works.
Working with my map, the numbers may be a little off. Paris appears to be more like 3 deg E, but it could be 2. Marsailles does look like 5 deg E. Venice looks like 12 deg E. Vienn appears to be 16 deg E. and Sophia appears to be 31 or 32 deg E.
My answer, curtesy of Charlie, is 31 or 32.
