if you are in the park during the daytime and plan to attend HHN, don't leave the park !!
ioa closes at 7:00
studios closes at 5:00 and clears the park out before hhn will start.
if you have the hhn ticket, you qualify to go to the stay and scream holding area. it usually will be in a resturant. you hang around there until the security and staff give the all clear to leave and start your hhn experience.
if you leave the park, you will have to stand in line outside the entrance gate until the general public is let in.
the lines are long, i have seen people in past years start to line up at 5:00.
and, you will have to go through the metal detectors.
think about the length of time you will lose just doing that.
be smart, do the stay and scream holding area.
if you have a day ticket to the park, you can buy the ADD ON ticket which is for the HHN event. it's at a cheaper rate. if you have the ap, no discounts this year for the epp.
