to swim in the Bahamas and CC. At least we were able to in 2000 and several people have reported the same as I recall from past threads.
The last time we did a 3 day it was still the Magic sailing alone and dinner was still a little dressier. Sounds like that may have relaxed a bit since then but still slacks are preferred in the dining rooms.
We did take jackets, and even in the summer when we've sailed sweaters were welcome in the diningrooms (air!) so I'd toss a lightweight something in.
Otherwise just regular vacation wear should do ya fine!
Enjoy!
