Here is a link to the website of the Hershey Region chapter of the AACA. There is an overall map and maps of each field.
I could not figure out how to find the swap meet spaces in the other thread until I found this.
The page at that link also says internet connection is $10 a day. When I travel I do my internetting at McDonald's, where wi-fi is free.
The $48 parking still gives me sticker shock. The AACA doesn't own the parking areas, and the folks who do really like getting lots of money.
