I booked the tour at 11 and went at 10:45, but the line was so long that I was able to enter at 11:25. I was late, so I had to stand in line without a reservation to get a ticket. I don't know why they ask me to make a reservation if I'm going to give you tickets like that The tour was also very long, but there wasn't much to see. I just took several pictures and came out. I don't want to recommend it.
