What they don't tell you about builder amenities

My kids' school admission is next year, and I still can't finalize a bigger flat. Pyramid Palm County ya CS Roseate Luxury Floors, in dono mein se kiska amenities ka promise real hota hai? Brochure mein sab kuch hota hai, but actual mein gym, pool ya kids' play area kaisa nikalta hai? Koi hidden charges ya RERA issues toh nahi hain?
