No, all evenings are of a casual nature although this doesn't stop the ladies wearing some very nice dresses (but not full length evening gowns), particularly in the specialist restaurants. The men don't normally wear jackets although one or two did when we were on there. Being in the Caribbean you will find the evenings quite a pleasant temperature out on deck so casual is appropriate and goes with the culture of the islands you will be visiting by day. I'm sure you will have a good time.
Thank you for taking the trouble to answer and I am looking forward to the cruise.
