My father was like you (back in the 1970s).
Unfortunately, he never talked to us children about his reasons and left us to our brainwashed mother.
In retrospect, I would tell my father (or you): please please talk to the children. Educate them about how cults work and how cults manipulate people. Educate them that they need to acquire KNOWLEDGE. Help them become critical thinkers and question everything. To question everything on its PROVABLE facts.
Ask the kids how they feel about having to do JW stuff. Find out if they enjoy doing it or are reluctant. Since the WTG always claims that it does not force anyone, allow your children to also say NO to a day out in service or a visit in the kingdom hall.
I love Portugal, especially the pleasant weather in the Algarve. I have been there many times - always combined with short trips to Lisboa.
