Are you travelling with children? We know how it goes, because we also have children.
If you want to be sure that not only your child will hear interesting legends but also you will get to know something about Kraków. If you are going to join with a baby stroller and the route should be adjusted to this. If any of these apply to you - choose this trip.
The time of the tour is relative and depends on the youngest ones. They can laugh without a reason and complain that there is no real dragon. It does not bother us :)
