As far as places to visit outside of Hersheypark, I enjoy Hershey Gardens, a beautiful and quiet 23 acre garden located on the hill below the Hotel Hershey. There are very nice flower gardens, rose gardens, and shrub plantings to stroll through as well as a wooded Japanese garden, an entertaining butterfly house, and a fun and interactive children's garden which is quite large. The entire property overlooks Hersheypark and its location offers almost aerial-like views of the park. If you have an appreciation for calmer activities, then it is something you should include in your trip. It also makes a good respite from the crowds of Hersheypark, much like ZooAmerica, and I like to break up my multi-day park trips with these quieter activities.
