I go almost every year since eighth grade to HHN in Orlando, and it is totally worth the money! I get a discount being a Florida resident, and Coca-Cola often does promotional sales where you buy a soda and get money off your ticket. A one day ticket from Sun-Thurs comes out to about $45, and I feel like it's worth the money.
I remember the first year I went there was a mental asylum house, and as soon as I walked in a nurse jumped out at me and I punched her. Yeah, I felt SUPER bad about it, but she scared me so badly.
Another year my dad got scared and bumped in to me, and I fell through the curtains in to the next scene, on to one of the actors dressed as Dracula. Super awk.
