Stayed 3 Nights. Nice place. Clean updated bathrooms, great pool, nice folks. There is a freight train that runs adjacent to the property but nice sites by the creek away from the tracks.
Great place to stay while going to Hershey Amusement Park - Free shuttle bus, discounted admission tickets and they let Hershey property guests in an hour early.
Also, just a mile drive to grocery, kmart, wine, and take out.
We've stayed at Highmeadows a couple of times and always enjoyed it. Trains were not a problem for us. Hmm. Might be time to think about going back again.
