If you think it will take seven days for a vacation, plan for eight or nine. If you think it will take four hours to drive to your vacation spot, prepare for five or six. Taking a time cushion will allow you to rest and not be upset because you are late or lost. If you are a single parent, you have the job of two parents to do when on vacation. Be kind to yourself and over prepare. That extra sweater just may come in handy if someone gets theirs wet and need a new one. Those extra snacks may keep the wild things calm when you are trying to find the right turn off on the highway in the middle of the night after being hours on the road. Time cushions allow you to handle the stressors that occur when taking a nontraditional family vacation.
