Or using the optional rules for long rests in the DMG like I do. I think 5E is far more flexible than 4E and doesn't require a ton of house rules to change the tone and pace.
That's it really.
4e healing surges is a better system for a basic fantasy adventure that happens over a day with meaningful tactically encounters within it.
5e hit dice is a worse base system but you can easily adjust it to fit a decent freeform, daily, hourly, weekly, biweekly, monthly, or encounter based system to your liking.
