In the olden days, stern parents wouldn't let kids jump on the bed until they had finished hopping on Pop. Now that fathers are keeping themselves in thinner, less hoppable shape, today's deal leaps forward with the changing times: for $12, you get a one-month unlimited open play pass at Jump Zone, an indoor inflatable theme park in Milford (a $25 value). Open play times are scheduled throughout the summer on both weekdays and weekends. For more bounce to the familial ounce, grab up to five Groupons. Although Jump Zone offers additional passes at $10 each after the first child's $25 pass, Groupon's max of five saves you $5 more than if you bought the same number through Jump Zone—so unless you're Octomom, today's Groupon is the better deal.

Jump Zone gives children of all ages, including ones that accidentally got transformed into Tom Hanks, 14,000 square feet of safe, clean, indoor playground space that includes eight monstrous inflatable structures. Let the rambunctious rascals loose through Batman's blown-up bat cave obstacle course, or lead a natural history lesson down King Kong's 20-foot slide. Pint-sized and pint-shaped toddlers can explore the scaled-down train tunnel and jump area, or walk on stable ground in the age-appropriate interactive zone. Jump Zone even accommodates illustrious royalty figures with a Disney Princess Castle primed for reenactments of such House of Mouse classics as Beauty and the Beast, Snow White and the Seven Dwarves, and Goodfellas.

With Jump Zone's open floor layout, parental units will never be more than a hop, skip, or jump away from their youngsters. Likewise, they'll be able to mingle in the central supervision area with friends their own age, be they a spouse or a misguided fan who came to get an autograph from Batman. For convenient carpooling and improved local camaraderie, socialize while the kids exercise on Friday evenings during family fun night.
