Coolgran, you sound very organised ("I could get dressed blindfold") Sometimes I think I look as if I've got dressed blindfold, which is not the same at all! I love colour, so I do have to be a bit strict with myself when packing, so as to ensure that most things go with most other things. Blue, turquoise, purple, green usually work well enough for me; plus white cotton trousers, navyish cropped trousers, assorted tops... and a sarong can be a skirt, a beach wrap, a towel, a shawl, a beach mat, even a top sheet for the bed if your bedding is too hot. A microfibre travel towel is fine for the occasional swim.
I am a bit cautious about health, and tend to travel with a large selection of tablets etc, just in case. I always carry a universal sink plug and a Swiss Army knife. If I need to wash any clothes, shampoo or shower gel will do the job well enough.
Packing cubes/pods: never tried these but seriously interested. Anyone care to advise me how best to use them?
