I borrowed this from another thread but it was the best I had seen. I hope it helps.
There are 3 levels of campsites at Fort Wilderness:
Standard, which includes electric and water This includes the 1500 and 2000 loops.
Full Hook Up, which includes electric, water and sewer (most of them are this way) This includes the 900, 1000, 1100, 1200, 1300, 1600, 1700, 1800, and 1900 loops.
Preferred, which includes electric, water, sewer and cable TV. As of the summer of 2005 high speed internet access was added to the preferred loops. The preferred sites are also in loops situated closer to the settlement which includes the marina, beach, restaurant, and many other activities. The preferred loops include the 100, 200, 300, 400, 500, 600, 700, 800 and 1400 loops.
The preferred and full hook up sites provide a full length concrete parking pad for the tow vehicle and camper. Behind that is a compacted sand/gravel pad on which you will find a full sized picnic table.
On the standard sites you will find a smaller concrete pad and larger sand/gravel pad. Also on each site is a charcoal grill.
