Normal
On the Island last week, people wore whatever made them comfortable. I didn't see too many sport coats in the dinning room except on formal night. I also saw many people in shorts in the Horizon Court in the evenings. It really depends on what I was doing during the day. If I was on a long day shore excursion and was tired, I would not feel like getting dressed for dinner so I would go to the horizon court in whatever I had on during the day. On formal nights you had a wide variety of clothes from ball gowns and tuxes to nice pants and sport coats. No one cared that I know of.
