DW and I are 45 with kids of 11 and 13. When we go, it's for the destination, and not as much for the journey, especially for the long trips out west or along routes we've already traveled and seen a lot of the sites.
We push hard to get to where we are going in order to maximize our time at the destination. In our case, we are usually on the road 14 to 16 hours a day and pulling into Cracker Barrel or Walmart (or others) at midnight, crawling into the camper and passing out. Get up the next morning and do it all over again. Wife is fine driving, especially with the new Ford, so that helps making those long days work easier. We've done rest areas and truck stops in the past, but they are darn noisy and I always feel bad using up a truckers spot for the night.
I understand that we all do things differently, and what we do works for us and not for others. I'm sure that after the kids are gone and time opens up, we'll probably change our habits a bit.
