Sailing with RC for the first time on Star of the Seas in a couple of weeks, I know there’s 2 formal nights as it’s a 7 night cruise. How can I find out which nights are actually formal, couldn’t find the info on the app. Also - are any of the nights themed? I saw that other cruises had like white nights or decade nights, just curious if Star partakes in any! Thank you!!
