Idea #3: Get lost in your own city.

Step one: Put on some comfortable shoes. Step two: Walk out the door. Step three: Resist the urge to develop a plan. Instead, just wander. Usually you're rushing to work, or the grocery store, or yoga class, but try to appreciate the joy of having no idea where you're going. If you see an interesting store, walk in. If you pass a tempting hot dog stand, indulge. Because when you're on vacation, the best way to discover a new city is to wander around for a few hours. It turns out it's also not a bad way to go on vacation in your own town.
