When my kids were young I took a set of those magnetized letters and words - the door was metal - and they wrote little poems and then passersby got into it and it was always fun to see what message was left for us. I also took those stick on gel decorations that I've seen people mention. Great to help my kids find their door! Many years later I'm finally taking another cruise and I will be getting something small to stick on the frame to help ME recognize my door. I enjoy seeing others creativity. For all those looking down their noses at decorations, I will just say - Have you ever been to one of those huge "personal care homes"? Rows and rows of sterile, undistinguished doors and I wonder how the elderly occupants tell which is "Home". I inquired and was told door decorations were not allowed. Made me very sad.
