I will be sailing on the Fortuna on 2/10 to the Eastern Caribbean and from what I understand other than the 2 formal nights it is casual for the main dinning room. Shorts are not a good idea for the dinners. My DH will be in slacks and golf type shirts, sportcoat not necessary, for the nights other than formal. For the ladies slacks & tops, sundresses, are the norm. I had the opportunity to be onboard the Fortuna for one night in Nov. prior to it's first Caribbean sailing and I thought the ship was beautiful. I have a group of 60 going with me on this sailing so it should be loads of fun. We will be boarding as you get off so look for 60 people in yellow t-shirts. Have a great cruise! Also be ready for the toga night, I've heard it is a riot!
