Yay. I finally booked my business travel to Europe!

I will be visiting Vienna, Austria for a few days on the way back. (I'm paying for the hotel myself, but my company is paying for the plane ticket.) Has anyone been there? Anything I should go see? I'm staying for 2 nights.

I'm excited that I finally got the travel stuff done, although my total travel time From Boston to Prague is 14 hours in one day. lol. (Touching down in Portugal as part of a connecting flight, with like 4 hours layover.) Hopefully I don't get hypo or anything.

Also going to Prague and Krakow. Anyone been there? Anything I should go see there? I can't do any tours unless they're night tours because I'll be busy from 8am-5pm while I'm there. I'll probably be hypo AF, tbh. lol.
