you dont really neeed to book tickets in advance. tours happen pretty often and there are a couple of guides on staff. I'd call them in advance just to be sure. i showed up unannounced for the last tour and there was no issue. cheers!
You really don't need tickets in advance, you can get them at the door, doesn't get crowded. Everyone there was very nice. I'm sure you'll enjoy the tour
We randomly went there and had no problem getting in the tour.
No need to book in advance! As long as you visit during regular business hours!
