really don't care if she goes or not but to expose the kids to nudes of all shapes and sizes is not right in my book.
You have two separate issues. Wife leaving the state and wife taking kids to a nudist resort. Focusing on attempting to prevent the wife from leaving the state attacks the issue you admittedly don't care about. You need to think more strategically.....and legally.
BTW, What does WW stand for, wayward wife?
