JBBS RC Enclave: The 'all-inclusive' pricing reality check

Loan pre-approved for JBBS RC Enclave, but I'm getting mixed signals on the 'all-inclusive' pricing. I work in real estate, so I know builders play super area vs carpet area games. What hidden charges did you guys face after booking? Especially interested in the actual amenity quality vs. what's shown. Is the clubhouse usable ya bas showpiece hai?
