Two local campgrounds if you can't stay onsite:Camping available? onsite?

Hershey Conewago Campground 717-367-1179 ( 1590 Hershey Road, Elizabethtown)
And congratulations to Pinkwhip and Belle!!! I'll try to come out and watch.
Edited to add a third campground: this one is closer to the Club, smaller, and there's more privacy:
