We really like Highmeadow and were there with a 35' TT bunkhouse. Sites are not large, but we had room between us to put out our slide and awning and had a few extra feet before our neighbors' awnings or slides.
As stated, it's close if you are going to Hershey park and has a shuttle running, at least in the summer. The pools are nice and the showers are adequate and were clean. I also used the laundry, but it was pricey - $2.50 for wash, $2.50 for dry, I believe.
When we go, we will stay there again.
