I didn't travel too far this week since everything is closed. The farthest I traveled was roughly 30 minutes to get to my friend’s apartment for our Thanksgiving dinner.
Here is where I've traveled to in order:
Bratislava, Slovakia - 1.5 hours away by train; day trip
Prague, Czech Republic - about 4 hours away by bus; stayed 2-3 days
Budapest, Hungary - about 4 hours away by train; stayed 3 days
Italy - Went to Ecrolano (near Naples and visited Pompeii from here) for 2-3 days, followed by Rome for another 3 days, and then ending in Bologna for another 2 days. Italy was about an hour and fifteen minutes away from Vienna by plane.
Public transportation. I take the U-Bahn (subway) and trams practically every day.
Honestly, the COVID vaccination site I saw was pretty cool and dystopian. Here is a short video showing how spacious this place is:
