Normally when we do HHN, we try to get in the gates as early as possible, don't recall what time...
Last year we went out to dinner with family around 4:00 or 5:00 o'clock and we didn't get to HHN until 6:30 - 7:00 o'clock.
What a bad decision.
Not only was it super crowded (even for a Sunday!)
but we weren't able to get into four of the haunted houses....
This year we will have a late lunch and get to HHN to take advantage of the WHOLE night! I suggest you do the same
