Combo: Palazzo Reale di Napoli e Villa Pignatelli con Ingresso Salta-Fila

I found the visit to the Royal Palace to be one of the must-see attractions in Naples, but the visit to the villa is only worth it if you take the opportunity to walk along the waterfront and explore another part of the city, different from the historic center (the villa itself isn't particularly impressive because it's small, some of the rooms are empty, and the carriage section is closed).
