Sector 1B upgrade: Metro, schools, resale confusion

Gurugram mein metro connectivity is still a pain point, especially last-mile. I'm in a 2BHK, eyeing a 3BHK in Sector 1B. Already have a home loan. Prices seem high. Is metro access good for daily commute? Kids ke schools bhi important hain. What's the resale market like here? Any ground reality checks for a family upgrade?
