I think people worrying about USF next year have to look at the overall resort situation. We learned during the last earnings report that 3/4 of all guests have park-to-park tickets. That means, for all intents and purposes, the resort is one big park for the vast majority of guests. Sure, USF will be a big park of walls next year, but that's also the year new Hulk and Kong will draw guests over to the other side. Then the next year you get F&F and Fallon. If you can get Nintendo open the year after that, don't you want to do it? I know I would.
You sacrifice a few months of crowded, wall ridden USF to get 3 years of big, legitimate additions in a row.
Also, I think a lot of people are overvaluing the draw of Twister, Disaster, and KidZone. Yea, having them all closed at once will be noticeable, but none of them were what guests were there to see
