Avoid this tour. It was disorganized, frustrating, and not worth the money.
Communication was a mess. Messages came through multiple channels, some were unsent by the host, and I couldn’t reach the host until the last minute before my entry time. It felt unreliable and stressful.
The audioguide was even worse. It was incomplete, didn’t cover all areas, the access code didn’t work, so I had to ask for another one, and the platform was confusing and difficult to use. The complete guide was not even opening. I had to go peace by peace, room by room in order to be able to use the audio guide.
This turned what should have been an enjoyable visit into a frustrating experience. Versailles itself is absolutely stunning, but do yourself a favor—book directly through the official website and use their audioguide instead.
