Sometimes we take the kids and other times we leave them behind and another option is to send the kids away and stay at home for adult fun.
When we take the kids we go places that the kids and us would enjoy. Our kids are teens who love being active so we do things like swimming, bowling, miniture golf, roller coaster parks, museums, art galleries, etc.
When we leave them behind and get away ourselves, we really don't plan too much having to do with the outside world. We just need a room, some delicious food, and time alone with each other to reconnect. The conversation is amazing.
We send the kids to relatives or to trusted friends houses where they have fun and we stay home. We watch a movie, eat, and relax. The New York/New Jersey area has so much to offer and to do.
