I'm not sure what it is called (and we received it actually as a present from a nephew)--you hang it in the bathroom and it hold toothbrush, dental floss, bandaids, hair brush, etc.
Also, of course my wife as I have no sense of direction and would have been lost several times. The worst was on our very first cruise as I got us on the train the wrong way from Livorno (the port for Florence and Pisa).
