Denise, I really don't notice what others are wearing either! However, I would like Radisson to maintain the civility of the line by enforcing the dress code. If someone doesn't want to put on a coat on informal night, then they have alternatives for dining choices. I, too, have to wear business wear for work. When I go on a cruise, I enjoy going up a step on informal and formal nights, and down a step on CCC nights. Wouldn't think of bringing any of those suits onboard! (Well, maybe my trusty black pant suit!)
Marc, your comments about disregarding the dress code leading to other inconsiderations reminds me of an experience from the past. I was a chaperone on a field trip when one of my children was in the 5th grade, and we were at the Science Center in Baltimore. One of the guards told me that kids in uniform (our school required them) always acted orderly and he never had a problem with them. Maybe there is something about "dressing" that makes people (adults and children) act differently?
