LeeAnne,
Crystal is also more formal than RSSC. We have friends that swear by them and they were disappointed in their one RSSC because of the entertainment and Country Club Casual. Different Strokes for Different Folks. They were also on one Crystal that had open seating because the ship was less than 50% capacity last year. They get a table for two and like fixed seating. I do not want to live by the clock or berushed through a meal on a cruise so no fixed seating for me!
