I bought concert tickets to the Kursalon in Vienna for myself, my husband, my cousin and two dear friends. I went on the Tripadvisor/Viator site 2 days prior to our leaving for Europe and no cancelation of the event was noted. We made arrangements with the cruise director to have transportation to the concert although the rest of the cruise ship passengers were attending a separate concert that evening. We went to the Kursalon and struggled to find out if there really was a concert and whether we were in the right place or had the right door. When we were finally told there was no concert I was devastated for the others in my group. I had lead them to what I thought would be a better concert. This is unacceptable. You can’t sell tickets to an event that is not held and expect to have a business that survives.
