It's too early to announce a date. I don't think there is much disagreement on that front.
That said, there is NO REASON the park can't pursue an aggressive marketing campaign without an official date to announce. Parks do that exact thing constantly. Iron Gwazi doesn't have an announced opening, and that doesn't stop BGT. InvadR literally had structural alterations ongoing mere days before it opened. That didn't stop marketing from continuously hyping the ride.
Again, a full time marketing employee walking down near the Pantheon site with a camera to post photos to social media is literally a half-hour process that takes essentially zero resources. People seem to think this needs to be some big production. It doesn't at all. I have no formal photography or marketing training. The park could give me access to the site for all of 15 minutes and I could easily get 10,000 unique impressions on those photos in 48 hours. Think of how much more BGW should be able to do with 24/7 access to the site, a team of marketing professionals, a staff photographer, etc. Not to mention that BGW has an EXPONENTIALLY larger social media following than BGWFans and they have a big email list of local journalists to put on blast whenever they want.
30 minutes worth of work on BGW's behalf should be able to result in hundreds of thousands of impressions for them. I don't understand their unwillingness to use the tools they have such easy access to. It's so goddamn frustrating.
PS: Another thing. So much of social media marketing is luck. Sometimes the engagement just happens to line up right and one post will explode out of the blue. So much of the name of the game is volume. You keep hitting the button consistently, and eventually, if your content doesn't suck, one of your posts will blow up—and there's where the real potential for reaching new audiences is. BGW hasn't been hitting that button a single time lately. They're just shooting themselves in the foot.
