Prestige City: Premium for empty amenities?

₹1.8 crore for a 3BHK in Prestige City — everyone talks about the 'luxury' amenities, but nobody discusses if those huge clubhouses are ever actually used. I'm currently in a 2BHK and paying a premium for a fancy but empty clubhouse seems crazy. Is it just a sales gimmick, or do people actually use those facilities daily? Change my mind.
