Ahh - I thought I had this all straightened out - I thought formal night was Sun night and semiformal on Thurs? I know there is a chart at the port telling us when signups are for Palos, Spa, etc.
But when/how will we definately know when formal & semiformal nights are? Has there been a change? Id hate to signup for Palos on semiformal night and have it be rotation night - Im trying for Palos on a night when I know DH will be out of his shorts!!

I called DCL to confirm my excursions this morning. I also asked them again what nights are formal & semi-formal for the Eastern. Like I thought - Sun is formal & Thurs is semi-formal. I got confused for a minute after I read someone's post. DCL said there has been some confusion because of the Eastern & Western routes having different formal nights.
