Re: A housekeeper?
If you say something like 'Gee I wish we could go to Lichtenstein this week, but we are going to have to do something closer to home and free, because the cleaner charges $ x', then the kids can see that the money can only go to one activity or another. Don't lay it on so thick that they think there is financial trouble, but let them know the 'disposable income' has been disposed of.
When our kids were teens, we gave them some choices as to what 'extra' money got spent on, and it did give them some sense of responsibility. We didn't have a housekeeper, but there were choices to make.
By the way just because there ARE 6 bathrooms, do they all need to be used? If possible, I would consider 'closing' a couple, guest use only.
