We were on a 7 day last october. we went the first couple nights to the dining room, but our table mates, were not friendly. we ended up meeting people at the champagne bar and had dinner with them at chops one night and we all had dinner at the windjammer from there on. we didnt have to dress up and could eat when we wanted.
we are booked for a 12 night med. cruise in july and are not taking any dress clothes for dinner. if i was with a big group, i would go to the dining room. but with 2 peeps, its a big risk of who your going to be put with.
