Same here. I personally don't think a year round haunted walk through makes sense for USH anymore, considering scary maze fans have HHN, and House of Horrors is far from all inclusive. It's a very "acquired taste" type attraction, and I personally think an actual ride would make better use of the space.
One could argue "what's the difference between a scary ride and a scary walk through". Well, a scary ride you have the "protective bubble" of your ride vehicle and there are animatronics and effects. In a walk through, it's a totally different sensory experience. You're walking through, and there are live actors. It's a very different feeling, one that I'm not a fan of. I'd rather have a House of Horrors ride with all the same characters but in animatronic form and be a bit more tame than the walkthrough, but a bit scarier than the Haunted Mansion.
