I took this tour in early Dec -- not the "high" season for tourism. The prison was open, but only 1-2 guided tours were scheduled since I wasn't with a school group. As I'd have had to wait more than an hour for the next tour, I went through the prison alone. There were explanatory signs posted and several tv videos playing, but no one to answer questions, etc. Only 2 wings of the prison were available to unguided tourists. My unguided tour of the site was interesting, but not worth the time it took to get to the site or the admission fee.
