Hi, all! I am 48 year old male and plan on taking a trip around April 2016. I plan on being in Europe for 89 days and then in England for 13 days. I plan on flying into Brussels and out of London via Aer Lingus. I am looking to break it down the following way: Brussels (5 days), Amsterdam (4 days), Bacharach (1.5 days, for the River/Castle Cruise), Frankfort (3 days), Nuremberg (3), Berlin (5), Dresden (3), Prague (5), Vienna (4), Istanbul (5), Athens (5), Rome (9), Florence (7), Venice (7), Milan (2), Genoa (3), Marseilles (5), Barcelona (4), Paris (8), and London (13).
I plan on using the main cities as bases and hitting the main sights, plus outlying areas while there. I am allotting $50 a day for food and $50 a day for various expenses (not food/travel related - more along the lines of museum passes, standing room opera passes in Vienna, and the like). My rail and air costs are included elsewhere, as are sleeping accommodations.
I used a great site that figures out cost between cities, My total breakdown comes to: travel between places ($1780), Hostels ($3500), Food ($4100), and spending money ($5000). Just shy of $16,000. Am I way off on cost estimation? Suggestions on changes?
