What town or city is between: Middletown, Marysville, Ickesburg AND Hershey?

I need to get a hotel room in Pennsylvania and I need to be in a city/town that is smack dab in the middle of all of them. Don't tell me it doesn't exist because PA is FULL of small towns and such :P. Also, I have perused all the websites for cheap clean hotels and not having any luck. So if you also have suggestions for that I would appreciate that too! Thanks in advance!
