They do have a shuttle at the zoo but you do have to pay extra for it. They say about half hour before your time starts
They recommend arriving at least 1/2 an hour b4 your scheduled time. The "Ghost Bus" is about a 10 minute ride to the prison. Better to prepay for parking online. It's cheaper.
It's not at the zoo. In fact if you go to the zoo, you will be in the wrong part of the city
The shuttle leaves about every 10-15 mins. You have to pay for parking before you leave the prison on the way back
