I'm sure I could "survive" on what I fit in a carry-on, but this is my vacation. Why should I? I much prefer to have options. I bring at least 8-10 swimsuits, most with a matching cover-up, several dresses, shorts, tops, and accessories. It all fits in my one checked bag, and is really no trouble at all. Life's too short to deny oneself the satisfaction of feeling good about myself.
