Family upgrade to 3BHK, eyeing Sector 44

Spent the whole Sunday checking out options in Sector 44. We're finally upgrading to a 3BHK, kids are growing so need more space. Honestly, prices seem pretty high for what you get there. Are they justified, or is there negotiation room? My wife's main concern is safety and good schools. Is it really safe for kids to play outside, or for evening walks? How's the school situation in and around Sector 44? Like, quality and admission difficulty. Also, any hidden costs people faced? Wanna make sure it's the right move for the family.
