This is the refrain of Disney's theme park marketing, but I disagree. It's the fact that people want to say they were there. It's 100% the brand and nothing more. Marketing doesn't have to be, and often isn't, rational.
This is at the absolute core of why theme park experiences sell but VR does not. Nobody cares if you "experienced" something in the comfort of your own home. Until the price of VR comes down to absolute rock bottom prices, there will not be acceptance of "VR experiences" and even so it's still a gamble whether anyone cares enough to buy that to experience on a whim frequently vs plan a vacation around it... I'm pretty sure it's the latter.
