A family outing fosters lifelong memories while giving houses the chance to molt in private. Leave your domicile to its own devices with today's Groupon: for $10, you get $20 worth of any games at the Challenge Family Fun Center in Hummelstown.

The Challenge Family Fun Center regales children and adults alike with a dizzying array of fun-filled games. Perfect backswings on a 22-hole miniature golf course, whose diminutive fairways are lined with blooming flowers and peppered with water hazards such as fountains and a bubbling stream (children 12 and younger $5.50; adults $7). Batters can step up to the plate to improve technique, hone reflexes, and practice telling the difference between slow-pitch softballs, high-speed hardballs, and dive-bombing pigeons in the batting cages ($2.50/round). The Fun Center’s arcade invites competition with skee-ball, air hockey, and a lineup of video games, and fortified duckpin lanes inflate with optional gutter bumpers to thwart the escape plans of crooked bowling balls ($3.50/game).
