I camp at Florence all the time. Your best option for camping with your family is going to be Driftwood II it is a nice paved camp ground with sites that back up the the trees so if you want to set a tent up you can do that also. Your other option would be sand dunes frontier. It is just a dirt camp ground with no showers so that kind of sucks. Here is the link to the site where you make reservations for Driftwood II http://www.recreation.gov/camping/Driftwood/r/campgroundDetails.do?contractCode=NRSO&parkId=70452&topTabIndex=Search if you have any questions just keep asking my family and I camp all the dunes here in Oregon several times a month.
