Everyone forgets how badly the resort was burned after the Potter announcement. AP sales cratered. Big EU reveal now, with the Mouse just reopening AP sales, plenty of guests going to sit it out the next two years, impacting two HHNs, two Christmases, two Summers and a Mardi Gras.
I will say even your 1 year estimate may be off, I've always heard 3 to 4 months. Granted we're in new territory here--no one has opened a major dry park in the social media era--but if Summer 2025 is the target for full operations, I wouldn't be surprised to see the real push reserved for January 2025. Let the locals fill up the soft openings that Spring.
