Itinenerary Austria, S Germany (maybe Switzerland) and Czech Republic..

Why don't you start out by looking at a few good guidebooks and getting an idea of exactly where you would like to go? Then we can better help you narrow down the best route.

You have chosen 4 very awesome countries. I have been to all and whatever you choose you will enjoy.

Germany, Austria and Czech Republic are in close proximity to each other.

Switzerland is SW of Germany.

Most important is doing the logistics and not back tracking.

Just remember to calculate and consider your travel days.

For your consideration....

Prague - 4 nights

Vienna - 4 nights

Salzburg - 2 nights

Munich - 3 nights

Lucern - 2 nights

Interlaken (Gimmewald) - 3 nights

Zurich - fly home

Here's Kent's post to help you calculate travel times between destinations:

This was our itinerary when we did those countries:
Prague, Czech: 3 nights (+ one night on night train to Munich)

Munich: 3 nights

Garmisch: 4 nights

Salzburg: 3 nights

Stuttgart: 4 nights

Now you could replace Stuttgart. We used to live there and like to go every few years to reminisce... Although, we used it as a base to see Strasbourg, France for a day. You could always replace Stuttgart with another city... Just to give you an idea of an itinerary that's been done!

Thanks everyone. I know it was a pretty open-ended question, but wanted to get some more expereinced travelers points of view.. Regards, Steve
