That's ridiculous, as he is!
As for the summer residence, it's certainly a very nice house with beautiful surroundings. IMO it's a pitty that her daughters' won't have the chance to spend more time there, to inherit it maybe. What if she sold it because she needed the money? I hope she talked about it with the girls, they're old enough for such a discussion. I understand that the house is connected with the time they spend as a family, including their father, and that could make it extra special for the girls.
