Alright let's clear a few things up here,
First off I never started the one ride per day rumor, I merely took a picture and tweeted the reride wait time sign in front of Hogwarts Express at the south station confirming it's been thrown around by operations. I said many other things about the HE months before anyone else but this "rumor" wasn't mine.
Second of all to say this land has been anything but a success shows a lack of looking deeper into the situation. We all know that Diagon holds a lot more people than Hogsmeade but what most people are not paying attention to is the difference between IOA in 2010 and USF in 2014. When Hogsmeade opened in 2010 people came for Potter and stayed for Potter. While wait times were outrageous in Hogsmeade other parts of IOA were practically empty and the Studios was a ghost town. In addition IOA was never built to handle the crowds people saw during the Summer of 2010. It was very unorganized and led to wait times that were much longer than were really calked for.
Fast forward to July 8th 2014 and it's a much different story. Again let's mention Diagons capacity which is more than double that of Hogsmeade. Then let's focus on what no one can argue. Wait times for other attractions in the Studios are longer. Simpsons, Transformers, DM, and the lot are doing exactly what there supposed to do by spreading crowds out. In addition the Studios is able to handle crowds much larger than that of IOA with ease. With the opening of Diagon many things were learned from 2010 and very much improved upon. No celebrities, parking garages opened at 5am, queues set up park wide for overflow of any attraction possible. Every manager, team lead, janitor, and every other type of team member was working crowd control and operations. Hell even park and resort executives, people from creative, and so on were there with name tags on making it as smooth as possible. They did such a good job that many people have this feeling it's been an unsuccessful addition to the park. Which couldn't be further from the truth in fact it's been so good that new doors have opened up. Finally what if I told you that on opening day of Diagon Alley double the number of guests entered USF then what did on June 18 2010 for phase 1...
So let's recap shall we, Diagon is a success plain and simple. If any trolls try to say otherwise just refer back to this post. Thanks!
PS: Fun Fact, Ollivanders in Diagon has 10 times more hourly capacity than Hogsmeade Ollivanders did when it opened in 2010.
