While I do agree that those completely unfamiliar with the premise of the series will be lost beyond help, the fact remains that the aforementioned people are few and far between. If you've not read the books, you've probably seen at least one movie and if you haven't seen the movies, you've probably heard about it at the very least. I think all three rides have storylines that are easy to follow and the immersive characteristics of both the rides and Hogsmeade make it so that you can still feel like you're part of Harry's world, even if you don't have a damn clue who this Potter fellow is.
And it's a hell of a lot to explain, too. I think Uni understands the scope of this franchise and has pulled it off rather well, given the budget and space.
