After reading several posts that folks took an over the door plastic shoe holder, I brought one on the Liberty cruise we just finished. Both my wife and I thought it was a little silly. However, much to our great surprise, it was one of the best recommendations we have ever received. It kept all the clutter off the vanity/desk area, we could find things immediately when we needed them and it really helped organize things for shore tours. We also take bungee cords not to open doors but to assist in carry purchases by tying bags/boxes on to our rolling suitcases. They are especially handy for liquor boxes
Keep the great ideas flowing.
