Drive no more than 200 miles in one day. Stop every two hours for a stretch break. Arrive at the campground by 2 p.m. Stay at least two nights at the same campground. This is the 2/2/2 rule.
The 3/3/3 rule is essentially the same but with threes. Drive no more than 300 miles in one day. Stop every three hours for a stretch break. Arrive at the campground by 3 p.m. Stay at least three nights at the same campground.One rule isn’t better than the other. It’s a matter of personal preference.
If Plan A fails, take a deep breath and have a Plan B. Most of the time, you’ll travel safely and happily from one place to another. But there will be days where everything seems to go wrong. If you have to make an extra stop because someone needs to stretch and walk, do it. If a kid gets carsick and you need to stop and stay overnight somewhere, do it. Don’t try to beat the clock.
Part of both the 2/2/2 rule and the 3/3/3 rule is arriving at your destination before dark. Actually, the goal is to arrive long before dark. But again, sometimes things go wrong, so it’s good to have a buffer.
