Switching to Gritty Realism is a big help in making sure you get a couple short rests in between long rests.
Another one I like is something I stole from Adventures in Middle-Earth. For that game you need Safety from threat of attack, Comfort, and Tranquility for a long rest.
So in my campaign, sleep for 8 hours on the road might not get you the benefit of a long rest, though you will still need to bed down every night to avoid exhaustion. It's just a tool I use to make sure Short Rests happen, and short rest based Classes get their opportunity to shine.
