Some things are more family friendly when done on a smaller scale, such as playing golf or sinking battleships. Enjoy an activity at its optimal size with today's Groupon: for $19, you get six rounds of mini golf at Mike Greenwell's Bat-A-Ball & Family Fun Park (up to a $39 value).

Owned by and named after the former Red Sox outfielder, Mike Greenwell's Bat-A-Ball & Family Fun Park entertains activity-deprived clans with a fully loaded complex of outdoor amusement for all ages. The synthetic green lawn of his mini-golf course snakes along a chain of 19 holes shaded by a canopy of palm trees and emerald markers. Children younger than 10 can expel energy that they held back while focusing on putts on the red, wooden jungle gym, while cars wait patiently in free parking spaces. Though not included in today's Groupon, the park also staffs eight batting cages, a paintball field, go-karts, a fish-feeding dock, an arcade, and a snack bar to further flesh out afternoons.
