Sleep setup
Make an Overnight Comfort Note
After the trip, write down what affected sleep in concrete terms. A slipping pillow and a noisy site call for different changes.
Start with the practical details
Separate site factors from equipment factors. If the tent fit well but traffic was distracting, changing the campground location may matter more than changing the shelter.
Make the plan flexible
Record what worked too, including where you kept nighttime essentials. This helps you preserve useful habits while adjusting one variable at a time.
Try this on your next trip
Choose one change to test on the next overnight. A short note will be easier to consult when you pack again.
