Holy Moly, I'm slippin' in my old age. When we were there in September we did the Segway tour. We stopped on the easterly side of the boat dock.
They took our picture from there with the Castle and Space Mountain in the background. That area was the permanent rope fencing that they put up recently, about 6' from the waterline.
Between the fence and the water was stakes with elevations written on them. I thought that they were from the fence installation, but now I'm wondering if it's for new beach?
It would be a great view of the fireworks from that vantage point
