I am going to be visiting Austria in June and will probably be doing a little solo siteseeing and travelling.

This will be my first trip to country where English is not the primary spoken language.

My question is, as an English-only speaker, how challenging will it be for me to find my way around places like Vienna and Salzburg, and especially the metro and train systems?

I will be buying some travel books, but wanted to also get some opinions here.

Thanks!
