I was there too!!
We got there around 6ish... (fear fest wasn't open yet)
So my friend and I rode Vortex, FOF and ITST (no lines )
and then we did do all the haunted Attrations. I was shocked that it was all empty, but which meant we got to do alot more than we'd expected. I don't know if anyone was in line for Headless Hollow when someone threw up and they had to fix the attraction before anyone could go through it. Me and a couple other people were the next ones to go through, and we had to wait a good 30-40 minutes until they said it was ok to do the trail... it was worth it though!!! THe staff was like "since we are all waiting, who wants to tell some ghost stories? or wait!! we can get in a circle and play telephone!" lol. It was awsome night!! It was more scarier since the park was dead, lol.
