A road trip can be a good choice for someone looking for family travel deals. Depending on where you are going and what gas costs, driving can be cheaper and easier than trying to fly.
I have a wife and four young kids and it is a nightmare trying to get everyone through the airport. We have a ton of luggage which these days costs extra. And keeping the kids behaved on the plane can really start to strain your patience. If it is reasonable to drive I will pick a car over a plane any day.
