Does anyone have information on the Glacier Express?
Is it worth it it go excellance class?
Is it better to go to from St. Moritz to Zermatt or the reverse?
Or just do part of the trip?
I see no difference going east-west or west-east. Excellence Class is over kill in my book unless you are the type of person that always flies Business Class to/from Europe and stays in 5-star hotels. Even 1st class, while nice, is not necessary. The exact same mountain scenery will be passing by outside those panorama windows no matter what class you pay for.
I took it from Zermatt to Chur. Excellent. Which way you go doesn't matter. The next day I took the Bernina Express to Tirano.
The train was crowded so I'm glad I treated myself to first class. Much more comfortable.
