That’s awesome (and helpful)!
I kinda want to be able to forget what day it is, but this means I only have to stick it to the door, and not into my memory.
I don’t need to be entertained everywhere I go, even walking down a hall, but still am thinking if a tiny “flair” item. But just for the family, not to keep other cruise ship passengers from getting bored, ya know, on a cruise ship.
