It looks like they use the "Sorin'" aspect mainly in the
primary dragon fight and the Quiddich match
. If they used it LESS than two times, I might say that they hardly used the KUKA arm to their full extent. The line to the ride is fantastic. It's like a mini-attraction unto itself! It sets up the main plot points:
1. You're a muggle invited to Hogwarts by Dumbledore and you're to go to a lecture
2. Harry, Ron & Hermione want to help you escape the lecture and go to a Quiddich match
3. A Dragon and Voldemort are also on the loose
And the whole ride seems like a basic storyline, too, tying everything together:
You get on flying benches (due to Hermione's Floo Powder) and you fly to a Quiddich game (AND PASS HAGRID! EPIC WIN!!) when SOMETHING GOES HORRIBLY WRONG and a Dragon knocks you off course (Plot Point #2), forcing you to go through several places from the books such as the Forbidden Forest, the Ballask chamber, and... I couldn't tell, did they get to the Chamber of Secrets? Anyway, then you FINALLY get to the game and (just when you think that Malfoy was going to be the nastiest thing at the game) DEMENTORS show up, of course sent by Voldemort (Plot Point #3). Harry saves the day with the help of his friends (Ron, Hermione, and YOU!) and a party is waiting for you in the Great Hall.
Also, isn't it clever that they use the "Room of Requirement" for the loading platform? Supposedly, in the books it can turn into any sort of room you want (provided it doesn't break any of the exceptions), so I guess park guests REALLY want to get on this ride because the room is a loading platform, as it appears here!
