From 2BHK to villa — my honest upgrade story

The disparity between promised amenities and what's actually delivered is my biggest worry right now. I'm currently in a 2BHK in Sector Alpha, thinking of upgrading to a 3BHK or maybe even a villa in Greater Noida. Parsvnath Privilege Phase IV looks good on paper, but I'm worried about what actually gets delivered. Are the clubhouses and sports facilities genuinely usable, or just showpieces? My biggest fear is paying high maintenance charges for services that aren't up to par. Also, how's the parking allocation there? Is it a lottery system or properly assigned? Already have a home loan, so the price jump needs to feel justified. What's been your experience with the actual usability and service quality in projects like this after possession?
