Big house to compact flat — my Noida search

Noida mein property dekh raha hoon, kids have moved out, so don't need such a big place anymore. Ajnara City jaise projects mein clubhouse, gym kaafi bade dikhate hain. But I wonder, kya log actually use karte hain? Ya sirf maintenance charges badhane ka tareeka hai? For an empty nester like me, is it worth paying for fancy facilities agar woh ghost facilities hi rehti hain? Resale value pe bhi fark padta hai kya?
