I had to 'dig out' the summer wear as we cruised in the winter and put them through a rinse cycle to freshen them up and then I ironed almost everything. (Judy-you would have been proud of me!lol) This was a couple of weeks before our cruise but the clothes were dug out before that to go through to choose outfits. I helped my daughters choose their clothes but let my husband do his own thing. We did take too much though!
We do have to be careful about overloading my husband's "poppa disc" huge suitcase.
We do not cross pack, but do take our bathingsuits in our carryons.
