Hi, I
I like the help I got from the book "How to Pack" by the travel experts Fodor's.
Just a couple of tips; don't take a lot of shoes. I only wore sandals, comfortable walking & one pair of dress for evening(black)
You will be in shorts, t-shirts, swimsuits most of the time. pack light. and if you are in the tropics wear light color clothing.
a light windbreaker in case of rain, maybe a sweater or shaw if you tend to get cold in the A.C.
I took an extra tote bag for shopping on the shore trips, that came in handy for dirty laundry going home.
Don't stress out over things, just enjoy!!!
Happy crusing
