No back up.

When you drive four hours to go camping, you can't back out. Not even if a certain one-year-old screams his bloody head off all night and you end up having to drive out of the campground into the parking lot and sit there for the rest of the night because you feel bad for the other campers.

BUT, not being able to back out has its perks. For us, it meant we were able to explore Acadia for the first time. We stayed in a breath-taking campground right on the ocean, went on a horse-drawn carriage ride, enjoyed the tidepools, and views and were overall really proud of ourselves for making it happen. And of course the kids had a good time. Even if they were tired.
