Remember though they sell that HHN ticket that gives you 3 hours at IOA before the event and then you enter in between the parks to HHN. I would think this will be a huge marketing push this year. Get guests down there early, see Potter town, eat at citywalk or in IOA, then head into HHN. With our passes expired that's about the only way I'm seeing HP this year, so I hope they do it!
