I agree and hope that people will continue. We are teaching our younger kids the importance of feeling comfortable dressing for dinner and the manners that go along with that.It's amazing what your perspective can be on this. Because people talk about dressing up vs. not dressing up I started paying attention. On our last 2 cruises both 7 day carribean I felt many more people were dressed up vs. not dressed up. We had late dining and I watched as the early dining people were leaving the dining room and all the people who were in the lobby taking pictures and waiting for the late seating.
So if you want to dress up do!! There will be plenty of people who do.
