Masaki, I have read cruise crazed review on the cc board. His experience was not the same as the one I had on 3 crystal cruises. I'm sorry he didn't care for crystal. Recenty there have been very negative review about Regent and Silversea from some passengers. all I can say is different strokes for different folks. We are all very lucky that we can choose the cruise line that best fits our needs.
If you don't like fixed dining times then Crystal might not be for you. Unfortunatley, the dining room cannot accomodate all the passengers at one time. However, they do have great alternatiave restaurants that help in allowing passengers have open seating on several evenings.
