I went on the Holland America line three yrs. ago Feb. We only had classes during the time at sea. I learned a lot from Karen Combs about using fabric to create illusions. I was disappointed in another class. The excursions were wonderful, Bahamas, St. Martain, etc. There were a couple of hours each day when we were allowed in the sewing rooms to work on projects. But my friend and I usually chose to be out on deck. If I did it again I would go with Royal Carribean. I've been on one of their cruises (not quilting) and loved it. The one crazythread described sounds fantastic.
