какой предлог употребить in или on?

  • Подскажите, какой предлог употребить во фразе "на балконе", in the balcony или on the balcony?

  • For balconies in such places as houses, apartment buildings, office buildings and hotels, native speakers say “on the balcony.” But for balconies in theaters, concert halls, and opera houses, they say “in the balcony.”

    Examples: John and Mary are having lunch on the balcony of their hotel room. When John and Mary go to the theater, they prefer to sit in the balcony.
