Eastern...

what night is formal and semi formal? Is it still the Sun and Thurs? (does DCL change this often? the last navigators I read were different days!)
Also, what night is the Twice Charmed show on? I want to make sure we take DD to see that!

Generally on the seven day Caribbean cruises, formal night is the First SEA day and semiformal is the Last SEA day. I believe this is pretty consistent regardless of whether it's Western or Eastern. On special itineraries, you just check for the SEA DAYS.
