It's ok to walk in for same day tours
I would book in advance to be safe but i believe you can just show up
On most days, during the daytime, you can just walk right up and buy a ticket from the ticket office. It's best to come early in the day as tours fill up quickly throughout the day as the day progresses. However, if there's a show, or special event in progress there may be no tours running during that time. It's best to call ahead, or purchase your tickets ahead of time if you want a guaranteed spot on a tour. The tours typically run every half hour and last for roughly 30 to 40 minutes. Bring your walking shoes. :)
Yes
We just walked in and went on the next tour.
I got mine online and printed them off. Alto easier.
Book online to avoid a wait. We waited 2 hours on site.
We went on a Monday and got right into the next tour. I imagine you might want to book online for a weekend.
