As someone who didn't start attending until 24, I don't get the same feeling from that video you posted. There is always a guest right in front of the person filming. Heck, even now it's very possible to go into a house with nobody in front or behind you. I did it multiple times at 25 and a few times during 26. Even when they start you off single file, most of the time halfway through the house, your not right on top of other people. Also, it seems just as loud throughout the whole video as it does for most of the newer houses. Ghost town had quite a few areas of quite that stand out, but nearly every house had it's quite areas.
I feel like you look back on the event, back when you were younger and things like crowds and loud noises didn't really bother you or even notice to much. Not calling you old by any means, but i'm sure every year had it's flaws. There will never, and can never be, a perfect HHN event.
