Here’s the sad truth. I’m a nerd. A huge, massive, Harry Potter nerd.
I’ve been to IoA twice and US once (read, US after Diagon Alley opened, Hogsmeade twice).
There are actually SEVERAL parts of both parks I’ve never stepped toe in. This trip I’m going with my DH only (he didn’t go with us for the prior two trips). He’s not into HP (although he knows a lot about it because he lives here), but will go for my happiness.
I will do my best not to spend my entire day in The Wizarding World.
So, what is not to miss at both parks outside of WWoHP?
(The only parts I’ve been to myself are Seussland & the part with Posiden’s Fury (because you walk through it) and Jurassic Park, plus whatever parts of US you walk through to get to DA.
