My friends stayed at Linn Run State Park last year in the snow and gushed about how relaxing it was. I don't think they were really impressed with the cabin itself, but it got them where they wanted to be.

I would check the DCNR web site and see if any state parks on the north/central part of the state have cabins you'd be interested in.
