Branson was well on it's way long before SDC got to be very big at all. In fact, by the time FITH opened in 1972 there were already a ton of theatres and famous performers calling Branson home. The damming of Table Rock Lake is actually what spurred the area into being a tourist town, with the country artists driving it after that. SDC grew at a steady pace, but it's hard to say when it really got "big". I'd say the 90's?
The AH park certainly does have a decent location in terms of access. I40 is a major artery and will make it easier for people from several surrounding states to get there. It's still not surrounded by much though other than Grand Lake. The thing is, there are already plenty of established parks around the country and plenty of lakes, so what will make them stand out?
The anti-woke stuff won't bring people in. People don't go on expensive vacations to protest Disney. I'm sure they have some things in the works however. They will surely roll out some characters, movies, etc somewhere in the timeline of this development. We'll see if they catch any eyeballs though...
Anyway, next time I'm running up to Branson I'm going to try and get off the highway to get a few construction shots. Probably not much to see from the road yet, but would be interesting to see how much activity is going on by the entrance. I imagine they have a big setup by now for the contractor staging since they'll be there for a few years.
