We were planning to camp Memorial Day weekend in Shenandoah but of course, we have not planned far enough in advance apparently, and all of the reserved sites seemed to be sold out. We were looking into Big Meadows or Loft Mountain Campgrounds arriving the Thursday before Memorial Day weekend and staying through Monday. It's about an 8 hour drive for us, and I really am nervous about driving all the way there and not getting a site! Anyone have any info about how fast these campgrounds fill up for the weekend? Thanks!
