See, I just don't see the event being that much better even if there wasn't construction going on everywhere. Besides a Jaws house, what exactly did the construction prevent? A scarezone b/t Shrek and S44? There's not usually any scarezone over in the Diagon Alley construction. Unless budgets were being diverted and time was a big problem, I don't see how construction impacted the event, and even considering budget and time, HHN is a whole different entity than the normal operation of the park--they all have their own teams doing their own things. So I'm not sure I buy the construction excuse.
Hopefully this year is a step back in the right direction.
