Yes, the land, not PART OF the land... FJ is what makes the land! Shops are a nice new complement, and Hippogriff and Dragon Challenge aren't new rides, just new theming. The main draw and main selling point is FJ. When people buy these packages it's for the HP experience, and the number one thing is FJ. Universal knows this. They made disclaimers saying that if FJ, Hippo, DC or Cat in the Hat were not functioning they'd open another attraction. That right there shows clearly that FJ and the other 2 re-themed rides are part of it. Whether they work or not, that's the issue, but they are selling the "package" not a "bundle of most of the WWoHP." There's no way around it.
About annual passes, they might not specify everything when they sell this to you, but it's understood. It's usual, it's tradition, and it's a selling point.
This applies to both my arguments: Not everything might be written and specified. Certain things don't need to be because it's known that it will be a certain way. FJ is the WWoHP. Annual passes have special benefits and annual passholder previews. These things are understood and obvious enough that they don't need to be explained in small print. And Universal knows these things are expected.
