Over the 3 day weekend I took a trip to Poland. Instead of using the exchanges like I usually do, I checked on localbitcoins for a seller. I arranged to meet him about an hour after I arrived at my hotel. He met me in the lobby and I sold enough bitcoins to get the local currency for the weekend.
My hotel was paid for through Expedia and my plane ticket paid with cheapair.com.
I even had lunch at a restaurant that accepts Bitcoin. All in all, a fun weekend paid for with bitcoins.
