Good points, I think you may very well be right. The exit by Dinoplay certainly could be used as an exit as well, though my dream is that's where DK will go out of lol.
Honestly, knowing how far along this land is and how much things have picked up, I think they really do want to get this done quickly. But the two major factors of not wanting to open lands in a tourism drought, which hit USH harder than other parks likely due to stricter COVID policies, and just general COVID delays prevented this. I'm guessing omicron really killed progress on this land for a while, the same way it killed what was supposed to be a massive Lunar New Year celebration, which is why things were moving slow for a while. Universal ain't that stupid.
