Hereshey was 3 years ago so I won't judge.
HITP and Storybook Land this year...and both were great and much different ways.
I loved how Storybook Land turned all the lights on at one time with the wave of Santa's wand. The light display in the back to music was much fun to watch and who doesn't enjoy a train ride through holiday lights. It was my first time at here and found the place to be a gem that should not go away.
At HITP the lights were on once dusk came so there was no big lights on event (I think they should do this). The main tree was every 30 minutes starting at 4:30 PM and what a tree show that is! I heard each second of the show took several hours to program. They had several holiday shows in areas of the parks..including an very nice one in the theater by chiller. There was also a huge change in the crowd at the park for the better. It was more families and smiles everywhere. No FastPass so everyone was treated the same (please keep it this way). The only thing I would change is turn down the scent boxes/scen spray a bit...at time the evergreen tree/cookie smell got a bit overwhelming. Great Adventure didn't need to be running the rides but that was a nice addition. Hopefully next year they add a few more lights and change up the show. Oh and don't even look at the Belgian Waffles! I heard they may add a round trip on the sky ride next year (I know Hershey does that) and Total Mayhem. This event probably added a new crowd to the season pass sales for 2016. Hopefully the park made out well from the event.
