We are on the same Vista 1 June Trieste cruise. So most important - it's nice to meet you virtually and maybe we will see you on the ship. With regard to your question, I had the same problem with not seeing my OBC transfer for our culinary class or gratuities I signed up for. I went ahead and paid with credit card so will see what happens once on board. The website says culinary classes and beverage packages (which lists gratuities) can be used with prepaid credits so hopefully all are covered. I'll have a shore excursion ready just in case though.
