Not sure which one you picked, but #2 on the list above is very easy and convenient to get to from Interstate 81. Plus, it's a very short and easy drive to Hersheypark from there. It's also in a quiet part of town, if that's what you're looking for. There's a diner within walking distance of # 2. I've never been there, but they seem to do a good business. Also, down the street a mile or two is a sports bar named Arooga's. The service can be slow when they're busy, but the food is very good.
If you want to avoid terrible crowds and traffic, check Hershey's web site and make sure there aren't any concerts going on. Traffic and crowds can be pretty heavy on days when there's a concert - especially a popular one. I don't think there's anything going on for the dates you mentioned in your signature, so you're probably good. Other than that, weekdays are your best bet for lighter crowds.
