Theme & Amusement Parks in Willow Grove

Inflated structures, slides, and games fill the climate-controlled environs of the numerous BounceU locations that speckle the nation. At each site, staff members closely monitor all activities as little ones traverse obstacle courses or pull on oversized inflatable boxing gloves. The crew also invites parents to join in on the fun, letting them bounce alongside their kids or make sweeping edicts from atop a bouncy-castle throne. In addition to open sessions, the indoor-play haven sets the stage for the Preschool Playdate program, where instructors lead games and activities. Special events include family-bounce night, which lets parents join in the bouncing or relax in the party room and do grownup things, such as eat marshmallows with a knife and fork.

Timothy Haskell is no stranger to scaring folks: The Daily Beast considers his Nightmare series "one of the most frightening haunted-house productions in New York City." But when he teamed up with haunted-house vet Steve Kopelman, Timothy didn't want to keep populating creepy corridors with imaginary ghouls. At Nightmare: Killers, the duo tap into the true terror inspired by historical and contemporary serial killers to explore the monstrosity of their actions and the celebrity and cultural obsession surrounding them. The New York Times lauds the attraction as “a taut, assured production that knows exactly what it wants to do (scare the hell out of you) and performs its task with ruthless, coldblooded precision."

In the lobby, a gallery of artwork, memorabilia, and items from or about famous serial killers primes guests on the haunted attraction's theme and provides a glimpse into the warped minds of the killers in question. At the front of the line, personnel can mark any willing visitor’s forehead with an optional scarlet X, which will grant the actors permission to interact with those victims for the next petrifying 20–25 minutes. Inside the haunt, rooms depict scenes based on Ted Bundy and the Zodiac killer, with the occasional cameo from pop culture’s most fearsome fictional figures. To heighten heart rates even more, visitors will also have to navigate twists and turns, fog, and uneven footing as they desperately try to avoid becoming each psychopath’s latest victim.

BounceU welcomes kids to descend upon an inflatable, climate-controlled playground where they can bounce and ricochet in safety. Along with birthday parties and group outings, BounceU hosts open-bounce sessions that let sock wearers of all ages imagine they're synchronized leapers in a futuristic moon performance as they carom around the inflatable stadium, expending energy with every leap. Adults are welcome to act like 8-year-olds and join the vivacious youngsters in the playground.

The inflatable arena also opens its buoyant doors to day camps, where boys and girls ages 5–10 spend half their time with brain-bolstering projects such as painting or reprogramming the remote to skip all news channels. After stretching the limits of their imaginations, kids then spend the other half of the day stretching the limits of their limbs on the inflatable playground.

Arnold's Family Fun Center's 200,000-square foot facility buzzes with flashing lights, bright colors, and adrenaline-fueled activities suitable for all ages. Guests use softball-sized bowling balls to bust birds masquerading as pins during rounds of duckpin bowling, and black-light mini golf plunges putters into the depths of an ocean reef as they fight radiant octopi and pirates. More than 75 go-karts speed around two racetracks, and bumper cars let drivers explore the safer side of road rage. Inside one of the largest arcades in the area, guests try their luck at more than 200 arcade games, including favorites such as Deal or No Deal, Big Buck Hunter Safari, and Guitar Hero. A bounce area keeps young feet busy, and a pizza and salad buffet refuel energy reserves before rigorous games of laser tag.

Lehigh Valley Grand Prix's gas-powered Sodi GT5 Proline karts zip around a quarter-mile racetrack with 11 brake-stomping turns. The karts feature air-intake units that trap their exhaust and keep the atmosphere fresh, and the track—constructed from 1,300 used Goodyear tires and the shredded remains of Mario Andretti's learner's permit—is outfitted with three observation platforms for track marshals to regulate each lap and guarantee riders' safety. A full-time mechanic keeps finish lines crowded by calibrating karts to run within three-tenths of a second of one another and hanging hundreds of piñatas from the checkered flag. At the facility's bar, Octane, drivers can refuel with drinks and food while watching stock-car races on the five 42-inch TVs.

For four decades, Putt-Putt Golf and Games has hosted friendly competition with four putt-putt golf courses and an array of games. Colorful blossoms and rocky waterfalls add character to 18-hole putt-putt golf courses, and creative hole designs add challenge. Groups of partygoers can request a staff chaperone to guide them through the labyrinth and hand over a treasure map to the course’s bounty of nougat-filled golf balls.

In the Game Zone, visitors settle competitive challenges at an air-hockey table or face-off against digital emissaries in the Terminator Salvation arcade game. Outside, the Jump Shot is a trampoline basketball hoop that launches athletes toward slam-dunks in lower orbit.
