I always overpack and bring clothes I don't wear while wearing some things twice. I have tried the last couple of times to downsize with a little luck, but not much. I will just have to keep trying I guess. I had a friend who almost drowned in Cozumel, so for several cruises I packed a "noodle" in my suitcase by wrapping it around the inside edges. I know people must have thought I was nuts carrying it to the beach
so I stopped carrying it.
I am amazed however of the people I see taking a small bag that will fit through the carry-on slot and that is all they take. I always figure that they pack underwear, flip flops and a couple of swim suits and nothing else.
