I guess I have the same feeling about this tipping for children. I have 4 children that will be on this cruise with us and I do all the work for them I probably won't make the beds but I will straighten them and I will make sure the room is picked up. I know that I have to tip and I do not mind that but I do not feel I should be told how much to tip actually when I get told I have to tip a certain amount it make me angry I tend to over tip when I am left to make my own decisions. That being said I will only be tipping half the amount for my kids as I will still be doing all the work and no one tips me!!!
Just my opinion for what it is worth.
