how close do you want to stay to home (ie what travelling distance from charlotte?) Also what are you looking for in a campground (ie amenities, hook ups etc)? There are lots of wonderful places to camp in NC.
Here is a thread from a post I had on another website asking about places to camp in the Charlotte area... http://www.rv.net/forum/index.cfm/fuseaction/thread/tid/25670878/srt/pa/pging/1/page/1
Also Jordan Lake in Apex near raleigh has some nice campgrounds (poplar point and crosswinds). This is water/electric only. There is a beach and you can fish (w/ NC fishing license). If you have a boat and get a waterfront site, many will bring their boat and beach it at the site (there is a boat launch at both campgrounds). http://www.ncparks.gov/Visit/parks/jord/main.php
If you are interested in a membership campground, we belong to Sycamore Lodge in jackson springs (near pinehurst). They are not cheap but they have a pool, hot tub, mini golf, shuffleboard, volleyball, nice playground, and a lake w/ paddleboats you can sign out.http://www.campnorthcarolina.com/
