But when you are "off", are you being paid?
In other words, do I have to pay her for every waking hour if she is away with us?
I'm glad it helped.
For that answer, you might need to sit down with your nanny to find out her expectations. Since she's asking to come with you on vacations, I'm guessing you're going somewhere she'd like to visit but might not be able to on her own?
It's hard for me to say because I'm not your nanny

Also, I don't know the location, how many kids, their ages, how many hours you'll expect her to work during the week, etc.
I'd look at where you're going and what your expectations are in terms of her helping you. I'd expect to pay her at minimum her normal weekly rate + travel/food expenses.
