Does this trimmed down version (eliminated Zurich

) seem better? Or should I trim further?
I wouldn't attempt this itinerary. You've got two full days in Paris, Rome and Venice and one full day in London and Barcelona. You need to trim some places to be able spend long enough in each city to make your travel time and costs worthwhile.
