Fright Dome is one of the worst haunted attractions I have ever attended. It started with operations staff that appeared to have no training, or at least training that was completely incorrect. A VIP Fast Pass was sold to allow quicker entry to mazes. And while the line was shorter than the standby line it still often was 30-45 minutes long or longer despite less than 20 people usually in that line. This comes from a poor system of pulsing groups into the mazes at entirely too slow of an interval. Often waiting several minutes before loading the next group despite this being totally unnecessary for the mazes as they don't utilize this extra pulsed time.
Scare tactics were as basic as possible and decor was plain, generic, and seemed like it came from a discount Halloween aisle. Perhaps one of the strangest elements of the mazes was the use of an in character guide to lead groups through the maze. These guides often made fun of the maze through their commentary and undercut the cheapness of the experience. This small amount of humor was the only redeeming element of the attraction, but only the first and second person in the group could even hear the dialogue, and I'm sure this comedic tone was not really the designed intention of these guides.
Fright Dome is not worth your time or money.
