Delhi's premium projects: green space & parking reality

Since April, I've been seriously shortlisting 3BHKs in Delhi. Currently in a 2BHK in Dwarka, so I'm thinking of upgrading. Already have a home loan, toh naye flat ka EMI jump kaafi bada hoga. Maitri Apartments type projects mein brochures mein green areas kaafi impress karte hain, but I'm worried about actual open space. Is it just for show, ya families ke liye usable hota hai, kids play kar paate hain? Also, parking allocation ka kya scene hai? Bahut jagah sunte hain ki lottery system hai ya bas ek spot milta hai, visitors ke liye toh nightmare ho jaati hai. Is this premium price really justified for these promised amenities, or are they just on paper? Not sure if the price jump is worth it agar daily life mein problems hi hon.
