Deertp Creek Lake Maryland campground recommendations?

Has anyone been to either Double G RV park or Bumble Bee RV parks in the D
Deep Creek Lake area? Any recommendations for other parks relatively easy for a newbie trailer owner in the general area? I have to go to a meeting up there the middle of July and this will be MY maiden voyage.
I know aabout Jennings Randolf Lake in West Va, but I don't want to tempt WVA mountain roads until I have more experience. (If you aren't familiar with Jennings Randolf Lake campground: It is very nicely set up, and getting there is almost straight up, but the real fun looks like coming back down.
