Since I was a bit faster I usually stopped around 4pm and Art arrived around 5. We'd be back on the trail, usually between 6 and 6:30 and walk for anywhere between one to two and a half hours. We always wanted some light when we set up camp.
Once in camp, we always had the option to snack. Sometimes yes, sometimes no.
The best thing about the late afternoon stop is that you can stop where it is convenient to clean up...usually near a lake or a creek, and where you have plenty of water for cooking, and provides a 2nd long rest break (lunch break was usually 30-60min, the dinner break usually 60-90min). Hiking a short distance (2-5 miles) afterward gives you many more options for camping.
