We got to go last year right after it opened and the lines were almost non-existant in the early mornings. I don't think a lot of people were aware it was open at first. Took a handful of pics that turned out ok if you would like to see. Really love how they kept it a lot like the original and not the tacky 70-80's version.
Forgot to mention, the entrance is on the backside of the castle, on the left hand side.
