Wow, they're efficient in getting back! Here's the lowdown....
"The Frozen night will be taking place on night two in conjunction with the Formal night. You will have the Frozen menu that evening. Normally Formal night takes place on an evening where you would have your regular rotation menu and does not have a specific menu associated with it. On Semi-formal night we do normally off the Captain’s Gala menu, which we will be offering on this sailing as well even though there is no Semi-formal evening."
Straight from the reindeer's mouth or something like that! I can ditch the Else wig, thankfully! ;-)
