A note: Before digging out the swimsuits and announcing the idea to the kids, be sure to call ahead, as schedules and rates can fluctuate.

Balls, slides, and more make this pool a real blast. Photo courtesy of Kroc Salvation Army Center

Kroc Salvation Army Center—Dorchester

With a two-story water slide, a heated lazy river, a "bubble bench," and 7 spray features, the Kroc is, legimately, an all-seasons water park inside the city. Though small, it's a blast for kids, and with rates of just $7 for children and $13 for adults, it's a steal compared to other indoor water parks beyond the city. Family locker rooms make this fun outing smoother than most, too.
