Just looking at past personal navigators, it seems like the same main show will probably be playing the first and second nights of our cruise. We are first time cruisers... if the same show is playing the 1st & 2nd nights, is there any reason to go the first night? I hear the 2nd night of our cruise will be formal night so I think when we're dressed up the show might be more fun than other activities. Plus, the first night we'll have plenty of exploring to do. Any advice for me?
