We went on Friday as well. I'm glad the rain held out.
I don't know if they were letting people in at 4.30 like they suggested, we got there just after 5 and walked straight in.
It was lots of fun. Kids enjoyed the hunt, but were disappointed that they got chocolate bullets at the lifesavers one. But us adults will eat those!
The spooky castle maze, I agree, the smoke machine was too much. Hard to breathe and everyone was coughing.
The queues were great, we didn't buy the extra passes and most rides you could just walk on with no waiting. We didn't do the vintage cars though as that one did have a queue. We did most of the rides, but skipped the little kids rides (my kids are 8 and 12).
We walked around anticlockwise, most of the crowd seemed to go the other way.
I though it was very well run. We didn't see any of the shows though as it was a fair walk around the park to do the hunt. We also grabbed McDonald’s after rather than eating there.
