I went to Congaree last week. It was pleasant, I would go again, we ended up hiking a bit over 5 miles on a beautiful day. Bugs were not an issue. Also saw Fort Sumter and USS Yorktown, went to a drive through Animal Safari, saw Biltmore in Asheville and drove on the Blue Ridge Parkway. Throw in a few state parks, saw a movie, had a few good meals and it was a pretty good road trip / van camping experience for my daughter and I.
