Others have failed to mention that you can look at the current cruise and see daily activities. It’s a bit harder to find now, but if you click on head icon in upper right, under your cruise, it says “select a different cruise”. Scroll to bottom and where it says Don’t see your cruise, click on let’s add it now. Then scroll down to “browse our ships”….from there, it will bring up the ships. Pick yours and then pick the current date.
I have noticed the Dress for the Day is usually around the 4-5pm mark.
Hope this helps.
