I don't know if this is a typical question that admins immediately close, but I am going to ask anyway.
I am from India. I have an opportunity to visit Frankfurt on Schengen visa. After my work is finished, I will have another week's time until I leave to India from Frankfurt. I would like to see as much as possible of Europe in this limited time. I would like to visit Paris, Amsterdam and Prague, and then I have to come back to Frankfurt to board my return flight. I have never been to Europe before.
Is a week's time enough to visit these places ? I just want to have a daytime's sightseeing in each city. Nothing extensive.
What is the economical and comfortable travel option from Frankfurt to Paris?
.. from Paris to Amsterdam?
.. from Amsterdam to Prague?
.. from Prague to Frankfurt?
In the (very unlikely) event that I still get extra time, I would love to visit Rome as well, any chances?
