Not really, generally we are unable to accommodate guests without a prior booking. Advanced ticket booking and reservations are required by the sites, and it’s essential to book the tour in advance to secure a space by a payment. While there may be last-minute openings on occasion, we cannot guarantee immediate availability. A place not paid is not booked.To ensure a spot, we recommend making a reservation ahead of time (for our walking tours, the bookings remain open untill the very last minute)
