been there many times... I love it!
I think with tour one you get the movie too... don't miss it.
You will be outside for some of the tour so dress accordingly. Some stairs involved so wear good comfortable shoes.
Ask lots of questions... a lot of freaky art from all over the world and all different eras, very eclectic, Every lamp, doorknob, ceiling, table, painting, sculpture, has a story.
If you like walking (a lot) it is possible to take more than one tour in a day.
Very cool place IMHO with lots of intersting history.
I'm toying with the idea of becoming a tour guide when I retire.
