We stayed the night at the Chateau and had a 10am reservation for the tour of the caves. We woke up earlier than expected and asked if we could switch it reservation for 9am and they let us. There were only 7 of us on the tour including the tour guide. She was very knowledgeable about the caves and the history of how they were "discovered". It was quite the experience knowing we were the first ones in the caves that morning and the caves were absolutely mind blowing. You must see to understand.
