If you are in SoCal, I can't reccomend going to Queen Mary Haunted Shipwreck this year.
It was a disaster. Ticket booth opened 45+ minutes late, the Shipwreck Productions manager was rude to me when I complained (he asked if I had been drinking, indicating he didn't care enough to even fake caring and thought my complaint was utterly without merit) and the lines were awful to get in.
The claim it was opening night problems; they been doing opening nights there for 9+ years. I've been going for 4-5 years and never had problems like this.
Beyond all this, the mazes weren't very good, some a complete rehash for several years in a row, the mechanical items weren't working, no fog machines at all and too many of the scare-actors weren't putting any real effort into it.
So for the SoCal Haunters, avoid Queen Mary Haunted Shipwreck this year. It's just not worth the ticket, the parking, the traffic or the overall effort of going.
