Many thanks to those of you who have answered my transportation questions thus far. I've read the info, checked The Man in Seat 61 website, and now I'd like to verify with you all that I have my facts straight.
To get to Bruges from Brussels airport, I can buy train tickets at the airport after I land for travel that day.
To get to Brussels Midi from Bruges, I can buy train tickets on the morning I want to travel.
To get to Salzburg from Munich airport, I can buy train tickets at the airport after I land for travel that day.
We've had so much weird stuff going on in our day-to-day lives these last few months that I feel compelled to check and double-check anything I'm not familiar with (and even a few things I was pretty sure I was familiar with but....)
Thanks!
