in some past years a special ticket was offered for about $20.
it allowed the person into the park an hour or two prior to closing time.
have not seen that available yet this year for hhn but wait in case it would pop up.
it came out after the sale of the hhn tickets.
i guess if sales are down for some nights, UO uses this tactic to get peeps into the park early and it increases sales.
if that type of ticket will be released this year, it will be a good way to be in the park, do a couple of rides and wait in the holding area once the park closes.
i have seen peeps start to line up prior to 5:00 on friday nights.
i don't see that happening for that last sunday of the event you are going.
the only headache of entering once the park reopens for hhn, is going thru the metal detectors.
if the person of you left their car keys in their pockets, it will hold up the line for you to get in.
especially if you are the one behind that person.
