So I visited the site yesterday and whilst construction hasn't started there are fences up because they are pulling down the wedding chapel that currently stands on the site.
Cranes are already at work removing this structure and land is being left unkempt in the area where construction is due to begin soon. This is going to be right next to Disney's Aulani with views over the Honu lagoon next to Disney's which it will share with time share apartments and villas to its south side.
This is the location close up marked in red is the land shown on the other photos including the current buildings.
The wedding chapel barried off from the lagoon side
Cranes on site and a gate left open.
The extent of the land that is being left ready for construction with Disney Aulani in the background. It's a big plot.
The grass here is in bad condition compared to the extremely well groomed areas nearby which makes me think it won't be long until they have work starting.
