How long before showtime should we arrive?

I agree at least an hour

75 mins so u would have more time to spend money before the show.....but 30 to 45 mins is plenty of time.

I got there 25 mins before and all was good

They recommend at least 75 minutes before show time so they can get you in and you can look around and than get you seated

At least an hour. Check out the village behind the castle!
