Hello! This is my first post to this site! I am taking 16 consecutive days in October to backpack Western Europe. This has kind of been a last minute adventure for me because I just found out that I have to conduct some business near Hannover, Germany and I wanted to take advantage of the free flight/travel over there. So I will vacation for 16 days, then conduct business and then spend the following weekend in a city prior to my flight back to the USA.
I am in need of some help planning how to best utilize my 16 days prior to my business and my weekend following my business. My trip will begin on Saturday, October 2rd and end on Sunday October 25th. I am pretty sure I would like to fly into Munich, Germany to catch the last two days of Oktoberfest. So here are some of my thoughts so far:

3 thru 7 – Munich (Oktoberfest, tour city, Dachau, Neuscwanstein, Salzburg) Take overnight train to Paris
8 thru 11 – Paris Take overnight train to Berlin
12 thru 14 – Berlin Take evening train to Prague
15 thru 16 – Prague Take Evening train to Vienna
17-18 – Vienna Get evening flight to Hannover
19 thru 23 – Work Flight or train to Amsterdam
24-25 – Amsterdam Afternoon flight back to USA on 25th

This itinerary and locations are not set in stone so I am very open to suggestions and other ideas. I was kind of interested in seeing Interlaken, Switzerland but didn’t think I could fit it in. Please let me know your experiences and thoughts! Also, I was researching the different train tickets to get. I am 29 years old so it appears as though I don’t qualify for the “youth” rail passes. I believe I should probably get the Eurail Global (10 days in 2 months) pass. I believe that this should work in the countries I have listed above and allow for some flexibility if something doesn’t go as planned. Does this sound right?
