If you are going to go to Scare Mare with a group of 25 or more, use their "Line Slasher" program. It is worth the extra dollar or two. We were in and out within an hour! One year we waited almost 6 hours to get in and out. Granted, it was good quality time spent with teens. But, quite boring.
We had a reservation at 8:45 PM but got there about 8:20 PM. We were done and walking back to our hotel by 9:15 PM! Incredible! They do a nice job and have over 30,000 people go through their event in three weekends. But, the fastest way is to go through line slashers.
The most fun part of the night is watching the girls scream. I have to admit I jump every now and then. But the girls make the night.
