When we go away, we tend to fill our days with things to see & do. We also tend to walk or take a cab to the places we’re going to. We try to simulate this at home. Sometimes that means parking the car in a central location.
Things we do when we don’t leave but have an extended break:
-Visit a museum we haven’t been to
-Take in a historical house, or settlement
-Go for a hike on a trail we haven’t been to
-Take a day trip to a community we haven’t been to (ideally one with shops, eateries, and unique local attractions).
Usually we then plan a nice take out meal in. For a 4-day weekend, we’d do one nice restaurant we haven’t tried yet.
When we stay in a hotel, we often watch a movie in bed together. This is something we don’t do at home. If you can think of something you typically do when you stay away—do that.
If you have the opportunity, do all of your errands prior to the 4-day vacation. That way your time off won’t be stolen away by the mundane.
I agree with @WestRiverrat: Act as if you are a visitor of your region.
