Old-Fashioned Play-For Pay Kids! Come to have a ball! Or 60,000 of them! There's a new type of business franchise that is appearing in shopping malls and neighborhood across America offering pay-per-use  indoor playgrounds, which feature toys, games, guided fun and a workout that doesn't break the family bank. As public playgrounds grow increasingly worn and dirty, the for-profit centers offer clean, safe guided activity as well as a variety of challenging exercises to develop kids' physical fitness, usually for a fee of around $ 5 an hour. "Playgrounds are dirty, not guided," says Dick Guggenheimer, owner of the two-month-old Discovery Zone in Yonkers, N. Y., part of Kansas City-based chain, "We are indoors; we are padded; parents can feel their child is safe". In order to satisfy the need of two-earner families, the new franchise stays open in the evenings, long after traditional public playgrounds have grown dark and unusable. However, these new playgrounds are not meant to be day-care centers. Parents are expected to go stay and play with their kids rather than drop them off. But several also provide high-tech baby-sitting services. At some of the Discovery Zones, parents can register their children in special guided programs, then leave them and slip away for a couple of hours to enjoy a movie or dinner. If there is a problem, Mom and Dad are called. The most fun of all, though, is getting to do what parents used to do in the days before two-earner families and two-hour commutes , play with their kids. That, at least, is old-fashioned, even at per-hour rates. According to the article, which of the following is TRUE to the new playground?
The cost is high for a family. It doesn't allow parents to leave their kids. It stays open in the evening just as traditional playgrounds. It's a place where parents can play together with their kids.
