Well, I went to Fright Fest (Six Flags New England) this weekend, and it wasn't quite all that I hoped for. It's advertised as..
"When the sun goes down.... Six Flags employees morph into ghosts and ghouls. Roller coasters become monstrosities in motion. And scares await you at every turn. See the park eerily transformed from coaster to coaster and ride haunted versions of your favorite rides."
They had some spooky sets sprinkled through the park (good photo opps) but none of the actual rides were any more spooky than usual. We spotted some spider around one coaster, but real spiders made those webs so the park employees can't take credit.
And there weren't many actors dressed up to scare the park guests. I saw maybe 6 all night, and their costumes weren't that elaborate. The best was probably the organ grinder and his screeching monkey:
Maybe if I had more time to see it all. But since the park "transforms" at dusk and closes at 10 PM, you don't have many hours to fit everthing in. We were able to find time for one coaster (with a 1 hour wait) and one haunted attraction (with a 2 hour wait).
The "Midnight Mansion" attraction was decent, but I've seen the same (or better) at local haunts. I guess I just expected a little more from a national theme park chain.
