Ticket prices change depending on the day of the week. Although, you can walk up to purchase tickets at the box office, it is best to purchase your tickets ahead of time on the website to ensure your desired time slot is not sold out.
They have a website. Now you know!
I would book as far in advance as possible
I went on a sat and the tickets where $40 for both houses but I think they're like $25 on Tuesday and Wednesday
Varies from $30 - $45+ depending on the day and if you want speed pass or not. You don't have to purchase ahead, online, but I recommend doing so to avoid a potential line to purchase on site.
