Here's what I know:
I've driven past it many,many times since about 1960, but have never been in it. From the outside, it always appeared to be geared to younger kids (I'd say under 10 yrs old). Their website seems to show that, too. Although if you look at it in Birdseye view on Bing Maps, they seem to have a fairly large roller coaster.
It's located just east of Lancaster, PA on US 30. This part of US 30 is basically a tourist trap, with Dutch Wonderland, an Amish Farm, outlet stores, etc. In many places it's a 3 lane road, with the middle lane swapping back and forth in direction. During the summer, it can get very congested.
A couple miles south is Strasberg, PA. Home of the Strasburg Railroad (steam train rides) and the PA Railroad Museum. Show the kids how railroading used to be.
