I've lived in Tung Chung for almost 2 years. All of the residential blocks have nice clubouses, pools, playroom, & some kids activities. E.g.Coastal Skyline has just started a parent toddler group (don't know what its like). Sunshine House in TC seems to get mixed reviews as does Greenfields (at Carribean Coast). Its only a short bus ride from Discovery Bay and I find there's more choice of playgoups there (kindermusic, funfit, first friends...) as well as a bunch of playgroups from fulltime to part-time
