They start a tour when they have 10 people for a group seems like one about every 15. To 30 minutes and the tour is scheduled for an hour but takes at least 90 minutes and can last a couple of hours. Not a tight schedule.
1 he 30min
The tours run about 1 hour 30 minutes. They can run multiple tours at one time if needed to keep things moving.
When i went they ran every 15 min. Due to the length of the tour they asked you be there the hour before they close.
Yes, its about an hour tour
They usually do tours through out as soon as a guide is available usually in groups of q2
Depends how busy it is! Seemed to be 15-30 minutes a group of 10-12 were let in. They make sure to ask how many people are in your group so you don't get seperated from them.
Show up any time after 1pm and the tour is an hour long in groups of 10 but i think they let people in every half hour
Like every 15mins or so if there is a line
