Our Magic cruise still 7 months away, but that doesn't stop our excitement!!! I've been reading many posts about these shoe hangers and how they are used. Tell me more. Where do you find them? (I've been looking in the luggage sections of Walmart/Target) and cannot find them. Do you carry them on board, filled or just use as a storage area in your cabin. What did you store in them? THANKS FOR ALL THE ADVICE!
