I have personally felt that the “opening season” is irrelevant, I would never book a March trip based on a “Spring opening”. Without a solid announcement date, I wouldn’t do anything. That’s just me though, it’s very annoying that they don’t stick to any timeline
Yeah, it was always vague in the past. Summer opening can be anywhere from May to August and that makes sense.
Disney has completely ruined it to where it can mean a year different to not at all.
