Maybe after you're back mention it in a text or email to avoid some drama? The only reason I would tell her is b.c. you don't want your kids to be the ones to do that and witness her reaction. I'm sorry you have to think about this OP. I've been in a similar boat.
Agree with this.
It's not your mother's business what your father chooses to do with his life, or with whom. I would go on an "ignorance is bliss" vacation which allows her, you and your kids to have a good time. When you get home, tell the kids and then tell your mother.
If, and when, she starts raging about it or making other negative comments you must hold firm and make it very clear that she is entitled to her opinions but she is not entitled to share them with you (or your kids.) Cut her off. Every. Single. Time.
