Lancaster County is no too far from Hershey. You can go to Dutch Wonderland(you can buy a pass that will give you admission to both Hershey Park, and Dutch Wonderland. You can go see all the Amish type attractions, the Strasburg Railroad is a lot of fun too. There are train museums in the area too. If you need Hershey Park info check out my info site at
www.hersheyinfo.com You'll find ticket info, park hours, all the info on Chocolate World, tons of pictures, ride info, menus.
Also I have a message board
www.hersheyboards.com there you can read info and click on links for area attractions.
You really could spend 3-4 days doing Hershey attractions. I could spend one day just in the new water park section of Hershey Park! Then there is all the entertainment in the park as well as the rides. Then Chocolate World with the free tour, 3D show, Trolley Tour, Factory Works, shopping, food and desserts! Plus the Zoo America! You get free admission with your park pass the day you are in the park. You could check out the Hershey resorts and have lunch or dinner at some of the restaurants at either or both resorts. Then there is mini golf and don't forget the outlet shopping too!
Let me know if you need any more help!
