Takemeaway - the over the door shoe holder is very useful on board ship. You can put anything and everything in it - hang it on the bathroom door and use it to hold toothpaste, toothbrushes, shampoo, etc. - anything that you don't want to have rolling off a shelf (even though the shelf in the lavatory has a rail on it) should you have some "rough seas". We used ours on our cruise last year and it was wonderful!!! DSs picked their own row of the holder to use and they kept their toothbrushes and combs in the pockets. For $1 it was money well spent!!!
