Our last ship was the Celebrity Millennium and before that the Century and Mercury. We still love the cruising experience. Love being at sea and thoroughly enjoy the more formal atmosphere. It is like Fantasy Island for one week. Very romantic! We would not enjoy seeing everyone wearing jeans in the dining room and hope that Celebrity maintains the more formal atmosphere. We have sailed NCL and didn't like drinking from paper cups in the cafe and the more casual feel. It didn't make us feel like we were being pampered like we do on Celebrity. We felt more like we were staying at a Holiday Inn. Maybe that is more the problem with some ships. People aren't feeling like they are being treated like royalty so the cruising experience isn't any different than hanging around home.
