We've always done 'traditional' second seating but on our next cruise (15 days Hawaii) we're going to give PC a try. We like the idea of eating when we want on our own schedule. Sometimes 2nd seating gets to be too late and you miss shows or feel like going to bed after dinner. We took a South Pacific cruise on Renaissance back in 2001 with pc dining and it was fabulous so we're hoping our experiences will be just as good. I like the idea of meeting new passengers and visiting especially if you've experienced being unhappy with your tablemates on a traditional dining schedule.
