I know it's late, but I figured I'd still post my experiences at this years fright fest.
Starting off at around 10:00 I noticed the "holding pen" before the entrance gates into the park was a little more crowded than before. In the previous years, the population wasn't too bad, but this year it seemed a little more full.
We rode Goliath first since it usually has a short line and then got in Line for drop of doom since it was likely to be crowded later. it was around 11:00 and we waited for about 5-10 minutes as they were really loading/unloading pretty quickly at the time. The ride overall was fun, but short. It's frickin high, it's over pretty quickly. I still liked it, but I prefer the bouncing aspect that supreme scream has at knott's.
We rode rides throughout the day, even the cheap ones like the bumper cars and scrambler. Just about every ride got checked off the list besides Ninja which had an unheard of 45 minute wait. Overall, the lines weren't too horrible and moved pretty quickly. The usuals like Scream and Viper(I rode this 10 times because of the short line) were practically walk ons which was great. What was a little frustrating was that a handful of rides were only using a single train. I understand the crowds aren't too heavy this time of year, but this caused a few rides, like Riddler and Ninja to have waits of around 30-40 minutes.
I was kind of underwhelmed by this years Fright Fest as it seemed very similar to the previous years. Even in a Friday, some of the lines were around 30 minutes long for short mazes that weren't entirely satisfying. I give six flags credit for trying, but waiting half an hour for Lecters Slaughterhouse is unheard of.
The mazes were decent this year, but many were incredibly similar to last year, which I have a problem with. Lecters and Jokers need to go in my opinion as the scares are virtually identical year after year after year. We didn't bother with Chupacabra because of how boring it was from last year. Blackout was ok, but not amazing. Black widow is the same story, not terrible, but not great. Aftermath is cool and all, but it isn't particularly scary. Nonetheless, its neat. Willoughbeys was probably the most impressive, and if the rest of the mazes followed in its footsteps, Fright Fest would be amazing. The effects were cool and the varying rooms were fun to look at.
We bought the regular wristbands ans none of us had season passes, and I don't think I'd advise otherwise. unless you do have a season pass, I wouldn't recommend the express wristband, because I don't personally feel the mazes are worth steep admission price.
