You're going to have a blast! Last year I went by myself, and it was also my first-time ever solo-traveling and also my first time in Europe. At first I was bit nervous, but once I started talking about STEEM with people and running into names that I recognized from online interactions (and of course after a couple drinks) the anxiety settled and it was really fun. It was definitely one of the best trips ever. @roelandp and the @firepower crew put on an extravagant event!
See ya in Krakow @coruscate!
