Waldorf, MD Indoor Activities

Bowl at one of the upscaliest bowleries in the city and feel like Jay-Z or Mason Andrews. Today's Groupon gets you an hour of bowling plus shoe rental at Mustang Alley's Bar Bowling and Bistro for $15 (normally $31.50). Though you won't be able to use this Groupon on Friday or Saturday from 7 p.m. to close, you can still bowl when the alley has its weekday specials, such as half-price wine bottles on Tuesday and half-price burgers on Wednesday.

Things are a little smaller at Glen Burnie Bowling Center, though the facility itself encompasses 30 lanes and a full-service snack bar, named GB Ducks Cafe. The petite objects in question are the pins and balls themselves. Glen Burnie celebrates the tradition of duckpin bowling, which incorporates lighter pins and smaller, easy-to-throw balls that almost never hatch into dragons. The objects collide during league games and open play. The smaller equipment also accommodates kids, and young bowlers can start playing in leagues as early as four years old. The coaches and instructors who oversee these programs hold certifications from the National Duckpin Youth Association.

With today's Groupon, $50 gets you a choice of three Pilates instruction packages at Mind-BodyFitness. Choose among 10 mat classes, two private sessions, or six group reformer classes. This isn't your typical introductory class discount—it's a complete instructional package designed to show you real results. At just $5 per mat class, $8.33 per reformer class, or $25 per private session, this deal is a no-brainer.

Ballyhooed by both Baltimore magazine and City Paper, Stoneleigh Lanes sets the scene for friendly bowling battles in a retro 16-lane alley. Strikers lace up rented kicks and hurl three-hole balls at 10 ivory duckpins. Sixteen-inch cheesy pizzas hush fifth-frame tummy grumbles, and sudsy pitchers of soda quench postpizza thirsts. The alley's BYOB policy lets bowlers imbibe brews brought from home, clearing out refrigerator space to be used for snowball storage. Handwritten scoring and gravity-feed ball returns enhance the spot’s retro charm.

Pilates is a low-impact, total-body discipline that focuses on the core to help keep the body balanced, toned, and energized. During the private equipment session at Fit to the Core Pilates, one of the studio's friendly and experienced instructors will teach you how to correctly use resistance machines, safely accommodating your skill level and fitness goals. Classes at Fit to the Core utilize STOTT PILATES equipment but also incorporate natural body resistance, stretching, and controlled breathing to build long, lean muscles while promoting physical and mental cohesion. Call ahead to schedule your one-on-one equipment session.

Across 5,000 square feet and two levels of obstacle-laden territory, taggers crouch around corners, rain lightning from the towers, and blend in with the dense vapor of the king's electric fog machine. During each 15-minute round, young squires can defend the keep for themselves or align with fellow beam archers in the name of the queen, the fiefdom, or love. To the victor go the bragging rights and a seat at the round table at home for family taco night.
