One positive outcome to UGB assuming they are able to pull through and get all the approvals they need to break ground, is that it will be the thing to get Disney to step up their game and invest in DLP far more. Because let's be honest, they clearly treat it as an afterthought in the parks portfolio.
The main DL park hasn't really received any large scale expansion since it opened in 1992, and what will become DAW still needs a lot of work, not helped by them moving at a comically slow pace for Frozen Post Covid. LK will likely be 2029 at the earliest and further additions won't happen well into the 2030s .
