Never done HHN. Just found out Walking Dead is a theme and my son and I love the show. Would it be worth it to go. What exactly is HHN other than going through houses where people jump out at you and scary people chasing you around. We love horror movies but is it really worth it. We would have to buy airline tickets (about 450), get a car rental, buy tickets (to both HHN and universal), get a hotel room so I would guess around 1,000 for a few days and my son would miss days at college. Is it really about 2 hours wait per house. And finally about how many houses would I really get to go through if I am there when it opens. Any help deciding would be so appreciated.
