Taking a Mother Daughter Vacation

I would really love to take a mother daughter vacation. The last time I tried to do this it ended up being a mother daughter and father vacation since my mom felt bad that we were going somewhere warm in the winter and my dad would be stuck staying in the cold. This time I would like to go to a luxury destination spa, which my dad wouldn’t be interested in. And now that they live down south the cold isn’t a reason for us to invite him along. I think maybe next time I will make it a father daughter vacation to make everything fair.
