That's a terrible comparison. Sorry. The houses are attractions themselves.. and HHN is packed with now 9 of those attractions, two shows, scare zones and streetmosphere, etc. That is worth the charge. You can do all the houses if you're at the gate right at opening and spend the whole night there. You can also take advantage of any kind of early entry via Passholder nights, Stay & Scream, etc. Is it relaxed and enjoyable this way? No, it's actually takes strategy and could be stressful. That's where Express comes in for those who prefer to waltz in at the times they do and still see everything.
How you can compare that to Disney who charges a ticket price for a castle show, parade, fireworks, some extra meet-and-greets, and candy? I love Not-So-Scary but let's be real here. You're getting way more bang for your buck, as an upcharge event, at HHN.
